Description

AUSTRALIA Regulation 3.2 Patents Act 1990 Complete Specification Standard Patent APPLICANT: Curis, Inc. Invention Title: TARTRATE SALTS OR COMPLEXES OF QUINAZOLINE BASED EGFR INHIBITORS CONTAINING A ZINC BINDING MOIETY The following statement is a full description of this invention, including the best method of performing it known to me: WO 2009/035718 PCT/US2008/056393 TARTRATE SALTS OR COMPLEXES OF QUINAZOLINE BASED EGFR INHIBITORS CONTAINING A ZINC BINDING MOIETY RELATED APPLICATION This application claims the benefit of U.S. Provisional Application No. 5 60/971,056, filed on September 10, 2007. The entire teachings of the above application are incorporated herein by reference. BACKGROUND OF THE INVENTION The epidermal growth factor receptor (EGFR, Erb-131) belongs to a family of proteins, involved in the proliferation of normal and malignant cells (Artega, C.L., J. 10 Clin Oncol 19, 2001, 32-40). Overexpression of Epidermal Growth Factor Receptor (EGFR) is present in at least 70% of human cancers (Seymour, L.K., Curr Drug Targets 2, 2001, 117-133) such as, non-small cell lung carcinomas (NSCLC), breast cancers, gliomas, squamous cell carcinoma of the head and neck, and prostate cancer (Raymond et al., Drugs 60 Supp/ 1, 2000, discussion 41-2; Salomon et al., Crit Rev 15 Oncol Hematol 19, 1995, 183-232; Voldborg et al., Ann Oncol 8, 1997, 1197-1206). The EGFR-TK is therefore widely recognized as an attractive target for the design and development of compounds that can specifically bind and inhibit the tyrosine kinase activity and its signal transduction pathway in cancer cells, and thus can serve as either diagnostic or therapeutic agents. For example, the EGFR tyrosine kinase 20 (EGFR-TK) reversible inhibitor, Tarceva@, was recently approved by the FDA for treatment of NSCLC and advanced pancreatic cancer. Other anti-EGFR targeted molecules have also been approved such as Iressa@. HN F I .ressa (ZD-1839) Tarceva@ 25 Despite the early success of Tarceva, it has become clear that selectively targeting individual kinases can lead to the development of drug resistant tumors.

I

WO 2009/035718 PCT/US2008/056393 Cells that have developed mutations within the drug/kinase binding pocket display a growth advantage in the presence of drug eventually leading to disease progression. Current clinical strategies aimed at combining these molecularly targeted drugs with standard chemotherapeutics, radiation, or other targeted agents will lead to novel 5 strategies to improve overall response rate and increase the number of complete remissions. Furthermore, elucidation of the complex and multifactorial nature of various diseases that involve multiple pathogenic pathways and numerous molecular components suggests that multi-targeted therapies may be advantageous over mono 10 therapies. For example, the use of EGFR inhibitors in combination with histone deacetylases (HDAC) has been shown to produce synergistic effects. Histone acetylation is a reversible modification, with dcacctylation being catalyzed by a family of enzymes termed HDAC's. HDACs are represented by X genes in humans and are divided into four distinct classes (J Mo/ Biol, 2004, 338:1, 17-31). In 15 mammalians class I HDAC's (HDACI-3, and HDAC8) are related to yeast RPD3 HDAC, class 2 (HDAC4-7, HDAC9 and HDAC1O) related to yeast HDAI, class 4 (HDACJ 1), and class 3 (a distinct class encompassing the sirtuins which are related to yeast Sir2). Recent advances suggest that EGFR-TK inhibitors in combination with 20 HDAC inhibitors may provide advantageous results in the treatment of cancer. U.S. Provisional Application No. 60/843,644, filed on September 11, 2006 and U.S. Provisional Application No. 60/895,873, filed on March 20, 2007, and USSN 11/852,604 filed on September 10, 2007, the contents of which are hereby incorporated by reference, describe quinazoline containing zinc-binding moiety 25 based derivatives that have enhanced and unexpected properties as inhibitors of epidermal growth factor receptor tyrosine kinase (EGFR-TK), HDAC and H ER2. It was surprisingly found that the compounds have enhanced activity when compared to the activities of separate molecules individually having the EGFR-TK and HDAC activities and combinations thereof. In other words, the combination of 30 pharmacophores into a single molecule may provide a synergistic effect as compared to the individual pharmacophores. The quinazoline compounds described above have been demonstrated as effective in decreasing tumor size in various animal models. It would be 2 WO 2009/035718 PCT/US2008/056393 advantageous to prepare pharmaceutically acceptable compositions, complexes and salts of these quinazoline compounds. SUMMARY OF THE INVENTION The present application is directed to tartrate salts or complexes of the 5 quinazoline compounds of formulae I-IV below.

In another embodiment, the pharmaceutical composition is a liquid formulation. In yet another embodiment, the pharmaceutical composition is an aqueous formulation, 30 such as an emulsion. In yet another embodiment, the liquid formulation is a parenteral formulation. In yet another embodiment, the formulation is an intravenous formulation. In a further embodiment, the composition is a dried formulation. Such formulations can be prepared by known methods including, for example, 29 WO 2009/035718 PCT/US2008/056393 lyophilization, spray-drying and/or super-critical fluid extraction. These solid concentrates can then be reconstituted at the time of or shortly before administration to a patient. In another embodiment of the invention, the composition comprises a 5 solubilizing agent. In one embodiment, the solubilizing agent is a cyclodextrin. Cyclodextrins are cyclic oligomers of dextrose with a truncated cone structure consisting of a hydrophilic exterior and a hydrophobic interior cavity. A cyclodextrin can form an inclusion complex with a guest molecule by complexing with all or a portion of a hydrophobic guest molecule within its cavity (for example, 10 as described in, U.S. Pat. No. 4,727,064, the contents of which are herein incorporated by reference). The size of the cavity is determined by the number of glucopyranose units in the cyclodextrin. Alpha- (a), beta- (B) and gamma- (y) cyclodextrins are the most common cyclodextrins and possess six, seven and eight glucopyranose units, respectively. Because natural cyclodextrins have relatively 15 low aqueous solubility and are associated with toxicity, chemically modified cyclodextrin derivatives have been developed to overcome these limitations. Such cyclodextrin derivatives typically possess a chemical modification at one or more of the 2, 3, or 6 position hydroxyl groups. Cyclodextrin derivatives have, for example, been described in U.S. Pat. Nos. 5,134,127, 5,376,645, 5,571,534, 5,874,418, 20 6,046,177 and 6,133,248, the contents of which are herein incorporated by reference and made a part hereof. As used herein, the terms "cyclodextrin," "a -cyclodextrin," "p-cyclodextrin and "y-cyclodextrin" are intended to encompass unmodified cyclodextrins as well as chemically modified derivatives thereof. In one embodiment, the cyclodextrin is selected from the group consisting of 25 a-cyclodextrin or a derivative thereof, p-cyclodextrin or a derivative thereof and a y cyclodextrin or a derivative thereof. In yet another embodiment, the cyclodextrin is a p-cyclodextrin or a deriviative or a 7-cyclodextrin or a derivative thereof. In an additional embodiment, the cyclodextrin is a -cyclodextrin or a derivative thereof. In a further embodiment, the cyclodextrin is selected from the group consisting of a 30 2-hydroxypropyl-p-cyclodextrin (Pitha et al, J Pharm Sci, 84 (8), 927-32 (1995)) and sulfobutyl derivatized-p-cyclodextrin (described, for example, in U.S. Patent Nos. 5,134,127; 5,376,645; 5,874,418; 6,046,177; and 6,133,248). In another embodiment, the cyclodextrin is a sulfobutyl derivatized-p-cyclodextrin. One such 30 WO 2009/035718 PCT/US2008/056393 sulfobutyl derivatized-p-cyclodextrin is sulfobutylether-7-p-cyclodextrin and is sold by CyDex, Inc. under the tradename CAPTISOL@. In yet another embodiment of the invention, the cyclodextrin is sulfobutylether-7-p-cyclodextrin. The cyclodextrin may be included in an amount that increases the solubility 5 of the active compound in the composition. In one embodiment, the amount of cyclodextrin included within the composition is the minimal amount needed to solubilize the drug in the composition. In yet another embodiment, the amount of cyclodextrin included within the composition is within about 5% of the minimal amount needed to solubilize the drug. In a further embodiment, the composition is a 10 parenteral formulation and the amount of cyclodextrin included within the formulation is the minimal amount of cyclodextrin needed to solubilize the drug.

In one aspect of the invention, the present invention provides for the use of one or more compounds of the invention in the manufacture of a medicament for the treatment of cancer. 10 In one embodiment, the present invention includes the use of one or more salts or complexes of the invention in the manufacture of a medicament that prevents further aberrant proliferation, differentiation, or survival of cells. For example, salts or complexes of the invention may be useful in preventing tumors from increasing in size or from reaching a metastatic state. The subject salts or complexes may be 15 administered to halt the progression or advancement of cancer or to induce tumor apoptosis or to inhibit tumor angiogenesis. In addition, the instant invention includes use of the subject compounds to prevent a recurrence of cancer. This invention further embraces the treatment or prevention of cell proliferative disorders such as hyperplasias, dysplasias and pre-cancerous lesions. 20 Dysplasia is the earliest form of pre-cancerous lesion recognizable in a biopsy by a pathologist. The subject salts or complexes may be administered for the purpose of preventing said hyperplasias, dysplasias or pre-cancerous lesions from continuing to expand or from becoming cancerous. Examples of pre-cancerous lesions may occur in skin, esophageal tissue, breast and cervical intra-epithelial tissue. 25 "Combination therapy" includes the administration of the subject salts or complexes in further combination with other biologically active ingredients (such as, but not limited to, a second and different antineoplastic agent) and non-drug therapies (such as, but not limited to, surgery or radiation treatment). For instance, the salts or complexes of the invention can be used in combination with other 30 pharmaceutically active compounds, preferably compounds that are able to enhance the effect of the compounds of the invention. The salts or complexes of the invention can be administered simultaneously (as a single preparation or separate preparation) or sequentially to the other drug therapy. In general, a combination 34 WO 2009/035718 PCT/US2008/056393 therapy envisions administration of two or more drugs during a single cycle or course of therapy. In one aspect of the invention, the subject salts or complexes may be administered in combination with one or more separate agents that modulate protein 5 kinases involved in various disease states.

Such targets include histone deacetylases (HDAC), DNA methyltransferase (DNMT), heat shock proteins (e.g. HSP90), and 25 proteosomes. In a preferred embodiment, subject salts or complexes may be combined with antineoplastic agents (e.g. small molecules, monoclonal antibodies, antisense RNA, and. fusion proteins) that inhibit one or more biological targets such as Zolinza, Tarceva, Iressa, Tykerb, Gleevec, Sutent, Sprycel, Nexavar, Sorafinib, 30 CNF2024, RGl08, BMS387032, Affinitak, Avastin, Herceptin, Erbitux, AG24322, PD325901, ZD6474, PD184322, Obatodax, ABT737 and AEE788. Such combinations may enhance therapeutic efficacy over efficacy achieved by any of the agents alone and may prevent or delay the appearance of resistant mutational variants. 35 WO 20091035718 PCT/US2008/056393 In certain preferred embodiments, the salts or complexes of the invention are administered in combination with a chemotherapeutic agent. Chemotherapeutic agents encompass a wide range of therapeutic treatments in the field of oncology. These agents are administered at various stages of the disease for the purposes of 5 shrinking tumors, destroying remaining cancer cells left over after surgery, inducing remission, maintaining remission and/or alleviating symptoms relating to the cancer or its treatment. Examples of such agents include, but are not limited to, alkylating agents such as mustard gas derivatives (Mechlorethamine, cylophosphamide, chlorambucil, melphalan, ifosfamide), ethylenimines (thiotepa, 10 hexamethylmelanine), Alkylsulfonates (Busulfan), Hydrazines and Triazines (Altretamine, Procarbazine, Dacarbazine and Temozolomide), Nitrosoureas (Carmustine, Lomustine and Streptozocin), Ifosfamide and metal salts (Carboplatin, Cisplatin, and Oxaliplatin); plant alkaloids such as Podophyllotoxins (Etoposide and Tenisopide), Taxanes (Paclitaxel and Docetaxel), Vinca alkaloids (Vincristine, 15 Vinblastine, Vindesine and Vinorelbine), and Camptothecan analogs (Irinotecan and Topotecan); anti-tumor antibiotics such as Chromomycins (Dactinomycin and Plicamycin), Anthracyclines (Doxorubicin, Daunorubicin, Epirubicin, Mitoxantrone, Valrubicin and Idarubicin), and miscellaneous antibiotics such as Mitomycin, Actinomycin and Bleonycin; anti-metabolites such as folic acid antagonists 20 (Methotrexate, Pemetrexed, Raltitrexed, Aminopterin), pyrimidine antagonists (5 Fluorouracil, Floxuridine, Cytarabine, Capecitabine, and Gemcitabine), purine antagonists (6-Mercaptopurine and 6-Thioguanine) and adenosine deaminase inhibitors (Cladribine, Fludarabine, Mercaptopurine, Clofarabine, Thioguanine, Nelarabine and Pentostatin); topoisomerase inhibitors such as topoisomerase I 25 inhibitors (Ironotecan, topotecan) and topoisomerase II inhibitors (Amsacrine, etoposide, etoposide phosphate, teniposide); monoclonal antibodies (Alemtuzumab, Gemtuzurnab ozogamicin, Rituximab, Trastuzumab, lbritumomab Tioxetan, Cctuximab, Panitumumab, Tositumomab, Bcvacizumab); and miscellaneous anti neoplastics such as ribonucleotide reductase inhibitors (lydroxyurea); 30 adrenocortical steroid inhibitor (Mitotane); enzymes (Asparaginase and Pegaspargase); anti-microtubule agents (Estramustine); and retinoids (Bexarotene, Isotretinoin, Tretinoin (ATRA). In certain preferred embodiments, the compounds of the invention are administered in combination with a chemoprotective agent. Chemoprotective agents 36 WO 2009/035718 PCT/US2008/056393 act to protect the body or minimize the side effects of chemotherapy. Examples of such agents include, but are not limited to, amfostine, mesna, and dexrazoxane. In one aspect of the invention, the subject salts or complexes are administered in combination with radiation therapy. Radiation is commonly 5 delivered internally (implantation of radioactive material near cancer site) or externally from a machine that employs photon (x-ray or gamma-ray) or particle radiation. Where the combination therapy further comprises radiation treatment, the radiation treatment may be conducted at any suitable time so long as a beneficial effect from the co-action oF the combination of the therapeutic agents and radiation 10 treatment is achieved. For example, in appropriate cases, the beneficial effect is still achieved when the radiation treatment is temporally removed from the administration of the therapeutic agents, perhaps by days or even weeks. It will be appreciated that salts or complexes of the invention can be used in combination with an immunotherapeutic agent. One form of immunotherapy is the 15 generation of an active systemic tumor-specific immune response of host origin by administering a vaccine composition at a site distant from the tumor. Various types of vaccines have been proposed, including isolated tumor-antigen vaccines and anti idiotype vaccines. Another approach is to use tumor cells from the subject to be treated, or a derivative of such cells (reviewed by Schirrmacher et al. (1995) J. 20 Cancer Res. Clin. Oncol. 121:487). In U.S. Pat. No. 5,484,596, Hanna Jr. et al. claims a method for treating a resectable carcinoma to prevent recurrence or metastases, comprising surgically removing the tumor, dispersing the cells with collagenase, irradiating the cells, and vaccinating the patient with at least three consecutive doses of about 10 cells. 25 It will be appreciated that the salts or complexes of the invention may advantageously be used in conjunction with one or more adjunctive therapeutic agents. Examples of suitable agents for adjunctive therapy include a 5HTi agonist, such as a triptan (e.g. sumatriptan or naratriptan); an adenosine A I agonist; an EP ligand; an NMDA modulator, such as a glycine antagonist; a sodium channel 30 blocker (e.g. lamotrigine); a substance P antagonist (e.g. an NKI antagonist); a cannabinoid; acetaminophen or phenacetin; a 5-lipoxygenase inhibitor (e.g., zileuton); a leukotriene receptor antagonist (e.g., montelukast or zafirlukast); a DMARD (e.g. methotrexate); gabapentin and related compounds; a tricyclic antidepressant (e.g. amitryptilline); a neurone stabilising antiepileptic drug; a mono 37 WO 2009/035718 PCT/US2008/056393 aminergic uptake inhibitor (e.g. venlafaxine); a matrix metalloproteinase inhibitor; a nitric oxide synthase (NOS) inhibitor, such as an iNOS or an nNOS inhibitor; an inhibitor of the release, or action, of tumour necrosis factor .alpha.; an antibody therapy, such as a monoclonal antibody therapy; an antiviral agent, such as a 5 nucleoside inhibitor (e.g. lamivudine) or an immune system modulator (e.g. interferon); an opioid analgesic; a local anaesthetic; a stimulant, including caffeine; an H 2 -antagonist (e.g. ranitidine); a proton pump inhibitor (e.g. omeprazole); an antacid (e.g. aluminium or magnesium hydroxide; an antiflatulent (e.g. simethicone); a decongestant (e.g. phenylephrine, phenylpropanolamine, pseudoephedrine, 10 oxymetazoline, epinephrine, naphazoline, xylometazoline, propylhexedrine, or levo desoxyephedrine); an antitussive (e.g. codeine, hydrocodone, carmiphen, carbetaper.tane, or dextramethorphan); a diuretic; or a sedating or non-sedating antihistamine. Matrix metalloproteinases (MMPs) are a family of zinc-dependent neutral 15 endopeptidases collectively capable of degrading essentially all matrix components. Over 20 NIMP modulating agents are in pharmaceutical development, almost half of which are indicated for cancer. The University of Toronto researchers have reported that HDACs regulate MMP expression and activity in 3T3 cells. In particular, inhibition of HDAC by trichostatin A (TSA), which has been shown to prevent 20 tumorigenesis and metastasis, decreases mRNA as well as zymographic activity of gelatinase A (MMP2; Type IV collagenase), a matrix metalloproteinase, which is itself, implicated in tumorigenesis and metastasis (Ailenberg M., Silverman M., Biochen Biophys Res Conmun. 2002 , 298:110-115). Another recent article that discusses the relationship of HDAC and MMPs can be found in Young D.A., et al., 25 Arthritis Research & Therapy, 2005, 7: 503. Furthermore, the commonality between H IDAC and MMPs inhibitors is their zinc-binding functionality. Therefore, in one aspect of the invention, salts or complexes of the invention can be used as MMP inhibitors and may be of use in the treatment of disorders relating to or associated with dysregulation of MMP. The overexpression and activation of 30 MMPs are known to induce tissue destruction and are also associated with a number of specific diseases including rheumatoid arthritis, periodontal disease, cancer and atherosclerosis. The salts or complexes may also be used in the treatment of a disorder involving, relating to or, associated with dysregulation of histone deacetylase 38 WO 2009/035718 PCT/US2008/056393 (HDAC). There are a number of disorders that have been implicated by or known to be mediated at least in part by HDAC activity, where HDAC activity is known to play a role in triggering disease onset, or whose symptoms are known or have been shown to be alleviated by HDAC inhibitors. Disorders of this type that would be 5 expected to be amenable to treatment with the compounds of the invention include the following, but are not limited to: Anti-proliferative disorders (e.g. cancers); Neurodegenerative diseases including Huntington's disease, polyglutamine disease, Parkinson's disease, Alzheimer's disease, seizures, striatonigral degeneration, Progressive supranuclear palsy, Torsion dystonia, Spasmodic torticollis and 10 dyskinesis, Familial tremor, Gilles de la Tourette syndrome, Diffuse Lewy body disease, Progressive supranuclear palsy, Pick's disease, intracerebral hemorrhage, Primary lateral sclerosis, Spinal muscular atrophy, Amyotrophic lateral sclerosis, lypertrophic interstitial polyneuropathy, Retinitis pigmentosa, Hereditary optic atrophy, Hereditary spastic paraplegia, Progressive ataxia and Shy-Drager 15 syndrome; Metabolic diseases including Type 2 diabetes; Degenerative diseases of the Eye including Glaucoma, Age-related macular degeneration, Rubeotic glaucoma; Inflammatory diseases and/or Immune system disorders including rheumatoid arthritis (RA), inflammatory osteoarthritis, juvenile chronic arthritis, Graft versus Host disease, psoriasis, asthma, spondyloarthropathy, Crohn's disease, 20 inflammatory bowel disease, colitis ulcerosa, alcoholic hepatitis, pancreatitis, Type 2 diabetes, Sjoegrens's syndrome, multiple sclerosis, ankylosing spondylitis, membranous glomerulopathy, discogenic pain and systemic lupus erythematosus; Disease involving angiogenesis including cancer, psoriasis, rheumatoid arthritis; Psychological disorders including bipolar disease, schizophrenia, mania, depression 25 and dementia; Cardiovascular diseases including heart failure, restenosis and arteriosclerosis; Fibrotic diseases including liver fibrosis, cystic fibrosis and angiofibroma; Infectious diseases including Fungal infections, such as Candida Albicans, bacterial infections, viral infections, such as Herpes Simplex, protozoal infections, such as malaria, Leishmania infection, Trypanosoma brucei infection, 30 toxoplasmosis and coccidlosis and haematopoietic disorders including thalassemia, anemia and sickle cell anemia. In one embodiment, salts or complexes of the invention can be used to induce or inhibit apoptosis, a physiological cell death process critical for normal development and homeostasis. Alterations of apoptotic pathways contribute to the 39 WO 2009/035718 PCT/US2008/056393 pathogenesis of a variety of human diseases. Salts or complexes of the invention, as modulators of apoptosis, will be useful in the treatment of a variety of human diseases with abberations in apoptosis including cancer (particularly, but not limited to, follicular lymphomas, carcinomas with p53 mutations, hormone dependent 5 tumors of the breast, prostate and ovary, and precancerous lesions such as familial adenomatous polyposis), viral infections (including, but not limited to, herpesvirus, poxvirus, Epstein-Barr virus, Sindbis virus and adenovirus), autoimmune diseases (including, but not limited to, systemic lupus, erythematosus, immune mediated glomerulonephritis, rheumatoid arthritis, psoriasis, inflammatory bowel diseases, 10 and autoimmune diabetes mellitus), neurodegenerative disorders (including, but not limited to, Alzheimer's disease, AIDS-related dementia, Parkinson's disease, amyotrophic lateral sclerosis, retinitis pigmentosa, spinal muscular atrophy and cerebellar degeneration), AIDS, myclodysplastic syndromes, aplastic anemia, ischemic injury associated myocardial infarctions, stroke and reperfusion injury, 15 arrhythmia, atherosclerosis, toxin-induced or alcohol induced liver diseases, hematological diseases (including, but not limited to, chronic anemia and aplastic anemia), degenerative diseases of the musculoskeletal system (including, but not limited to, osteoporosis and arthritis), aspirin-sensitive rhinosinusitis, cystic fibrosis, multiple sclerosis, kidney diseases, and cancer pain. 20 In one aspect, the invention provides the use of salts or complexes of the invention for the treatment and/or prevention of immune response or immune mediated responses and diseases, such as the prevention or treatment of rejection following transplantation of synthetic or organic grafting materials, cells, organs or tissue to replace all or part of the function of tissues, such as heart, kidney, liver, 25 bone marrow, skin, cornea, vessels, lung, pancreas, intestine, limb, muscle, nerve tissue, duodenum, small-bowel, pancreatic-islet-cell, including xeno-transplants, etc.; to treat or prevent graft-versus-host disease, autoimmune diseases, such as rheumatoid arthritis, systemic lupus crythematosus, thyroiditis, Hashimoto's thyroiditis, multiple sclerosis, myasthenia gravis, type I diabetes uveitis, juvenile 30 onset or recent-onset diabetes mellitus, uveitis, Graves disease, psoriasis, atopic dermatitis, Crohn's disease, ulcerative colitis, vasculitis, auto-antibody mediated diseases, aplastic anemia, Evan's syndrome, autoimmune hemolytic anemia, and the like; and further to treat infectious diseases causing aberrant immune response and/or activation, such as traumatic or pathogen induced immune disregulation, 40 WO 2009/035718 PCT/US2008/056393 including far example, that which are caused by hepatitis B and C infections, HIV, staphylococcus aureus infection, viral encephalitis, sepsis, parasitic diseases wherein damage is induced by an inflammatory response (e.g., leprosy); and to prevent or treat circulatory diseases, such as arteriosclerosis, atherosclerosis, vasculitis, 5 polyarteritis nodosa and myocarditis. In addition, the present invention may be used to prevent/suppress an immune response associated with a gene therapy treatment, such as the introduction of foreign genes into autologous cells and expression of the encoded product.

In one embodiment, the active compounds are prepared with carriers that will protect the compound against rapid elimination from the body, such as a 10 controlled release formulation, including implants and microencapsulated delivery systems. Biodegradable, biocompatible polymers can be used, such as ethylene vinyl acctatc, polyanhydrides, polyglycolic acid, collagen, polyorthocsters, and polylactic acid. Methods for preparation of such formulations will be apparent to those skilled in the art. The materials can also be obtained commercially from Alza 15 Corporation and Nova Pharmaceuticals, Inc. Liposomal suspensions (including liposomes targeted to infected cells with monoclonal antibodies to viral antigens) can also be used as pharmaceutically acceptable carriers. These can be prepared according to methods known to those skilled in the art, for example, as described in U.S. Pat No. 4,522,811. 20 It is especially advantageous to formulate oral compositions in dosage unit form for ease of administration and uniformity of dosage. Dosage unit form as used herein refers to physically discrete units suited as unitary dosages for the subject to be treated; each unit containing a predetermined quantity of active compound calculated to produce the desired therapeutic effect in association with the required 25 pharmaceutical carrier. The specification for the dosage unit forms of the invention are dictated by and directly dependent on the unique characteristics of the active compound and the particular therapeutic effect to be achieved, and the limitations inherent in the art of compounding such an active compound for the treatment of individuals. 30 The pharmaceutical compositions can be included in a container, pack, or dispenser together with instructions for administration. Daily administration may be repeated continuously for a period of several days to several years. Oral treatment may continue for between one week and the life of the patient. Preferably the administration may take place for five consecutive 45 WO 2009/0357 18 PCT/US2008/056393 days after which time the patient can be evaluated to determine if further administration is required. The administration can be continuous or intermittent, e.g., treatment for a number of consecutive days followed by a rest period. The salts or complexes of the present invention may be administered intravenously on the first 5 day of treatment, with oral administration on the second day and all consecutive days thereafter. The preparation of pharmaceutical compositions that contain an active component is well understood in the art, for example, by mixing, granulating, or tablet-forming processes. The active therapeutic ingredient is often mixed with 10 excipients that are pharmaceutically acceptable and compatible with the active ingredient. For oral administration, the active agents are mixed with additives customary for this purpose, such as vehicles, stabilizers, or inert diluents, and converted by customary methods into suitable forms for administration, such as tablets, coated tablets, hard or soft gelatin capsules, aqueous, alcoholic or oily 15 solutions and the like as detailed above. The amount of the salt administered to the patient is less than an amount that would cause toxicity in the patient. In certain embodiments, the amount of the salt that is administered to the patient is less than the amount that causes a concentration of the compound in the patient's plasma to equal or exceed the toxic level of the 20 compound. Preferably, the concentration of the salt in the patient's plasma is maintained at about 10 nM. In one embodiment, the concentration of the salt in the patient's plasma is maintained at about 25 nM. In one embodiment, the concentration of the salt in the patient's plasma is maintained at about 50 nM. In one embodiment, the concentration of the salt in the patient's plasma is maintained at 25 about 100 nM. In one embodiment, the concentration of the salt in the patient's plasma is maintained at about 500 nM. In one embodiment, the concentration of the salt in the patient's plasma is maintained at about 1000 nM. In one embodiment, the concentration of the salt in the patient's plasma is maintained at about 2500 nM. In one embodiment, the concentration of the salt in the patient's plasma is maintained at 30 about 5000 nM. The optimal amount of the salt that should be administered to the patient in the practice of the present invention will depend on the particular compound used and the type of cancer being treated. 46 WO 2009/035718 PCT/US2008/056393 DEFINITIONS Listed below are definitions of various terms used to describe this invention.

Over activity can also be the result of ligand independent or constitutive activation as a result of mutations such as deletions of a fragment of an EGFR-TK responsible for ligand 10 binding. The phrase a "radiotherapeutic agent" refers to the use of electromagnetic or particulate radiation in the treatment of neoplasia. The term "recurrence" as used herein refers to the return of cancer after a period of remission. This may be due to incomplete removal of cells from the initial 15 cancer and may occur locally (the same site of initial cancer), regionally (in vicinity of initial cancer, possibly in the lymph nodes or tissue), and/or distally as a result of metastasis. The tern "treatment" refers to any process, action, application, therapy, or the like, wherein a mammal, including a human being, is subject to medical aid with 20 the object of improving the mammal's condition, directly or indirectly.

As used herein, the term "pharmaceutically acceptable salt" refers to those 25 salts which are, within the scope of sound medical judgment, suitable for use in contact with the tissues of humans and lower animals without undue toxicity, irritation, allergic response and the like, and are commensurate with a reasonable bcnefit/risk ratio. Pharmaceutically acceptable salts are well known in the art. For example, S. M. Berge, et al. describes pharmaceutically acceptable salts in detail in 30 J. Pharmaceutical Sciences, 66: 1-19 (1977). The salts can be prepared in situ during the final isolation and purification of the compounds of the invention, or separately by reacting the free base function with a suitable organic acid or inorganic acid. 51 WO 2009/035718 PCT/US2008/056393 As used herein, the term "pharmaceutically acceptable ester" refers to esters which hydrolyze in vivo and include those that break down readily in the human body to leave the parent compound or a salt thereof. Suitable ester groups include, for example, those derived from pharmaceutically acceptable aliphatic carboxylic 5 acids, particularly alkanoic, alkenoic, cycloalkanoic and alkanedioic acids, in which each alkyl or alkenyl moiety advantageously has not more than 6 carbon atoms. Examples of particular esters include, but are not limited to, formates, acetates, propionates, butyrates, acrylates and ethylsuccinates. The term "pharmaceutically acceptable prodrugs" as used herein refers to 10 those prodrugs of the compounds of the present invention which are, within the scope of sound medical judgment, suitable for use in contact with the tissues of humans and lower animals with undue toxicity, irritation, allergic response, and the like, commensurate with a reasonable benefit/risk ratio, and effective for their intended use, as well as the zwitterionic forms, where possible, of the compounds of 15 the present invention. "Prodrug", as used herein means a compound which is convertible in vivo by metabolic means (e.g. by hydrolysis) to a compound of the invention. Various forms of prodrugs are known in the art, for example, as discussed in Bundgaard, (ed.), Design of Prodrugs, Elsevier (1985); Widder, et al. (ed.), Methods in Enzymology, vol. 4, Academic Press (1985); Krogsgaard-Larsen, 20 et al., (ed). "Design and Application of Prodrugs, Textbook of Drug Design and Development", Chapter 5, 113-191 (1991); Bundgaard, et al., Journal of Drug Deliver Reviews, 8:1-38(1992); Bundgaard, J. of Pharmaceutical Sciences, 77:285 et seq. (1988); Higuchi and Stella (eds.) Prodrugs as Novel Drug Delivery Systems, American Chemical Society (1975); and Bernard Testa & Joachim Mayer, 25 "Hydrolysis In Drug And Prodrug Metabolism: Chemistry, Biochemistry And Enzymology," John Wiley and Sons, Ltd.

As used herein, "pharmaceutically acceptable carrier" is intended to include any and all solvents, dispersion media, coatings, antibacterial and antifungal agents, isotonic and absorption delaying agents, and the like, compatible with 30 pharmaceutical administration, such as sterile pyrogen-free water. Suitable carriers are described in the most recent edition of Remington's Pharmaceutical Sciences, a standard reference text in the field, which is incorporated herein by reference. Preferred examples of such carriers or diluents include, but are not limited to, water, saline, finger's solutions, dextrose solution, and 5% human serum albumin. 52 WO 2009/035718 PCT/US2008/056393 Liposomes and non-aqueous vehicles such as fixed oils may also be used. The use of such media and agents for pharmaceutically active substances is well known in the art. Except insofar as any conventional media or agent is incompatible with the active compound, use thereof in the compositions is contemplated. Supplementary 5 active compounds can also be incorporated into the compositions. As used herein, the term "pre-cancerous" refers to a condition that is not malignant, but is likely to become malignant if left untreated. The term "subject" as used herein refers to an animal. Preferably the animal is a mammal. More preferably the mammal is a human. A subject also refers to, for 10 example, dogs, cats, horses, cows, pigs, guinea pigs, fish, birds and the like. The salts or complexes of this invention may be modified by appending appropriate functionalitics to enhance selective biological properties. Such modifications are known in the art and may include those which increase biological penetration into a given biological system (e.g., blood, lymphatic system, central 15 nervous system), increase oral availability, increase solubility to allow administration by injection, alter metabolism and alter rate of excretion. The synthesized compounds or tartrate salts or complexes thereof can be separated from a reaction mixture and further purified by a method such as column chromatography, high pressure liquid chromatography, or recrystallization. As can 20 be appreciated by the skilled artisan, further methods of synthesizing the compounds of the formulae herein will be evident to those of ordinary skill in the art. Additionally, the various synthetic steps may be performed in an alternate sequence or order to give the desired compounds. Synthetic chemistry transformations and protecting group methodologies (protection and deprotection) useful in synthesizing 25 the compounds described herein are known in the art and include, for example, those such as described in R. Larock, Comprehensive Organic Transformations, VCH Publishers (1989); T.W. Greene and P.G.M. Wuts, Protective Groups in Organic Synthesis, 2d. Ed., John Wiley and Sons (1991); L. Fieser and M. Fieser, Fieser and Fieser's Reagents for Organic Synthesis, John Wiley and Sons (1994); and L. 30 Paquette, ed., Encyclopedia of Reagents for Organic Synthesis, John Wiley and Sons (1995), and subsequent editions thereof The compounds described herein may contain one or more asymmetric centers and thus give rise to enantiomers, diastereomers, and other stereoisomeric forms that may be defined, in terms of absolute stereochemistry, as (R)- or (S)- , or 53 WO 2009/035718 PCT/US2008/056393 as (D)- or (L)- for amino acids. The present invention is meant to include all such possible isomers, as well as their racemic and optically pure forms. Optical isomers may be prepared from their respective optically active precursors by the procedures described above, or by resolving the racemic mixtures. The resolution can be 5 carried out in the presence of a resolving agent, by chromatography or by repeated crystallization or by some combination of these techniques which are known to those skilled in the art. Further details regarding resolutions can be found in Jacques, et al., Enantiomers, Racemates, and Resolutions (John Wiley & Sons, 1981). When the compounds described herein contain olefinic double bonds, other 10 unsaturation, or other centers of geometric asymmetry, and unless specified otherwise, it is intended that the compounds include both E and Z geometric isomers and/or cis- and trans- isomers. Likewise, all tautomeric forms are also intended to be included. The configuration of any carbon-carbon double bond appearing herein is selected for convenience only and is not intended to designate a particular 15 configuration unless the text so states; thus a carbon-carbon double bond or carbon heteroatom double bond depicted arbitrarily herein as trans may be cis, trans, or a mixture of the two in any proportion. In some embodiments, the inventive compound is a crystalline or an amorphous form of a compound of the invention. In another embodiment, the 20 inventive compound is a mixture of two or more crystalline forms of the compound. In a further embodiment, the invention is a crystalline form or a mixture of two or more crystalline forms of compound 12. A crystalline form of compound 12 can be prepared substantially as described in Example 8 (Method 2) below. Different crystalline forms of chemical compounds (or polymorphs) each 25 exhibit different physical, chemical, spectroscopic and/or crystallographic properties. In one embodiment, the crystalline form of the invention has an X-ray powder diffraction (XRPD) pattern with at least three, four, five, six, seven or eight major peaks in common with the X-ray powder diffraction pattern of the crystal prepared according to working Example 8 (Method 2). A major peak is an XRPD 30 peak with a relative intensity greater than about 25%; relative intensity is calculated as a ratio of the peak intensity of the peak of interest versus the peak intensity of the largest peak. As used herein, a peak for the crystalline form is in common with the XRPD pattern of the crystal prepared according to Example 8 (Method 2) if it is within 0.50 20 of a peak location for the crystal prepared according to Example 8 54 WO 2009/035718 PCT/US2008/056393 (Method 2). In another embodiment, the crystalline form of compound 12 has an endothermic transition within about 1.0C as the crystalline form prepared according to Example 8 (Method 2). In yet another embodiment, the crystalline form of compound 12 has an endothermic transition (as observed by differential scanning 5 calorimetry) within about O.5*C of as the crystal formed according to Example 8 (Method 2) and at least three, four, five, six, seven or eight major peaks in common with the XRPD pattern of the compound prepared according to Example 8 (Method 2). In a further embodiment, the crystalline form of compound 12 exhibits a differential scanning calorimetry pattern that is substantially the same as the 10 differential scanning calorimetry pattern of the compound produced according the Example 8 (Method 2). Pharmaccutical Compositions The pharmaceutical compositions of the present invention comprise a therapeutically effective amount of a compound of the present invention formulated 15 together with one or more pharmaceutically acceptable carriers or excipients. As used herein, the term "pharmaceutically acceptable carrier or excipient" means a non-toxic, inert solid, semi-solid or liquid filler, diluent, encapsulating material or formulation auxiliary of any type. Some examples of materials which can serve as pharmaceutically acceptable carriers are sugars such as lactose, glucose 20 and sucrose; cyclodextrins such as alpha- (a), beta- (B) and gamma- (y) cyclodextrins; starches such as corn starch and potato starch; cellulose and its derivatives such as sodium carboxymethyl cellulose, ethyl cellulose and cellulose acetate; powdered tragacanth; malt; gelatin; talc; excipients such as cocoa butter and suppository waxes; oils such as peanut oil, cottonseed oil, safflower oil, sesame oil, 25 olive oil, corn oil and soybean oil; glycols such as propylene glycol; esters such as ethyl oleate and ethyl laurate; agar; buffering agents such as magnesium hydroxide and aluminum hydroxide; alginic acid; pyrogen-free water; isotonic saline; Ringer's solution; ethyl alcohol, and phosphate buffer solutions, as well as other non-toxic compatible lubricants such as sodium lauryl sulfate and magnesium stearate, as well 30 as solubilizing agents, coloring agents, releasing agents, coating agents, sweetening, flavoring and perfuming agents, preservatives and antioxidants can also be present in the composition, according to the judgment of the formulator. 55 WO 2009/035718 PCT/US2008/056393 The pharmaceutical compositions of this invention may be administered orally, parenterally, by inhalation spray, topically, rectally, nasally, buccally, vaginally or via an implanted reservoir, preferably by oral administration or administration by injection. The pharmaceutical compositions of this invention may 5 contain any conventional non-toxic pharmaceutically-acceptable carriers, adjuvants or vehicles. In some cases, the pH of the formulation may be adjusted with pharmaceutically acceptable acids, bases or buffers to enhance the stability of the formulated compound or its delivery form. The term parenteral as used herein includes subcutaneous, intracutaneous, intravenous, intramuscular, intraarticular, 10 intraarterial, intrasynovial, intrastemal, intrathecal, intralesional and intracranial injection or infusion techniques. Liquid dosage forms for oral administration include pharmaceutically acceptable emulsions, microemulsions, solutions, suspensions, syrups and elixirs. In addition to the active compounds, the liquid dosage forms may contain inert diluents 15 commonly used in the art such as, for example, water or other solvents, solubilizing agents and emulsifiers such as ethyl alcohol, isopropyl alcohol, ethyl carbonate, ethyl acetate, benzyl alcohol, benzyl benzoate, propylene glycol, 1,3-butylene glycol, dimethylforrnamide, oils (in particular, cottonseed, groundnut, corn, germ, olive, castor, and sesame oils), glycerol, tetrahydrofurfuryl alcohol, polyethylene 20 glycols and fatty acid esters of sorbitan, and mixtures thereof. Besides inert diluents, the oral compositions can also include adjuvants such as wetting agents, emulsifying and suspending agents, sweetening, flavoring, and perfuming agents. Injectable preparations, for example, sterile injectable aqueous or oleaginous suspensions, may be formulated according to the known art using suitable dispersing 25 or wetting agents and suspending agents. The sterile injectable preparation may also be a sterile injectable solution, suspension or emulsion in a nontoxic parenterally acceptable diluent or solvent, for example, as a solution in 1,3-butanediol. Among the acceptable vehicles and solvents that may be employed are water, Ringer's solution, U.S.P. and isotonic sodium chloride solution. In addition, sterile, fixed oils 30 are conventionally employed as a solvent or suspending medium. For this purpose any bland fixed oil can be employed including synthetic mono- or diglycerides. In addition, fatty acids such as oleic acid are used in the preparation of injectables. The injectable formulations can be sterilized, for example, by filtration through a bacterial-retaining filter, or by incorporating sterilizing agents in the form 56 WO 2009/035718 PCT/US2008/056393 of sterile solid compositions which can be dissolved or dispersed in sterile water or other sterile injectable medium prior to use. In order to prolong the effect of a drug, it is often desirable to slow the absorption of the drug from subcutaneous or intramuscular injection. This may be 5 accomplished by the use of a liquid suspension of crystalline or amorphous material with poor water solubility. The rate of absorption of the drug then depends upon its rate of dissolution, which, in turn, may depend upon crystal size and crystalline form. Alternatively, delayed absorption of a parenterally administered drug form is accomplished by dissolving or suspending the drug in an oil vehicle. Injectable 10 depot forms are made by forming microencapsule matrices of the drug in biodegradable polymers such as polylactide-polyglycolide. Depending upon the ratio of drug to polymer and the nature of the particular polymer employed, the rate of drug release can be controlled. Examples of other biodegradable polymers include poly(orthoesters) and poly(anhydrides). Depot injectable formulations are 15 also prepared by entrapping the drug in liposomes or microemulsions that are compatible with body tissues. Compositions for rectal or vaginal administration are preferably suppositories which can be prepared by mixing the compounds of this invention with suitable non-irritating excipients or carriers such as cocoa butter, polyethylene 20 glycol or a suppository wax which are solid at ambient temperature but liquid at body temperature and therefore melt in the rectum or vaginal cavity and release the active compound.

In such solid dosage forms, the active compound is mixed 25 with at least one inert, pharmaceutically acceptable excipient or carrier such as sodium citrate or dicalcium phosphate and/or: a) fillers or extenders such as starches, lactose, sucrose, glucose, mannitol, and silicic acid, b) binders such as, for example, carboxymethylccllulose, alginates, gelatin, polyvinylpyrrolidinonc, sucrose, and acacia, c) humectants such as glycerol, d) disintegrating agents such as 30 agar-agar, calcium carbonate, potato or tapioca starch, alginic acid, certain silicates, and sodium carbonate, e) solution retarding agents such as paraffin, f) absorption accelerators such as quaternary ammonium compounds, g) wetting agents such as, for example, cetyl alcohol and glycerol monostearate, h) absorbents such as kaolin and bentonite clay, and i) lubricants such as talc, calcium stearate, magnesium 57 WO 2009/0357.18 PCT/US2008/056393 stearate, solid polyethylene glycols, sodium lauryl sulfate, and mixtures thereof. In the case of capsules, tablets and pills, the dosage form may also comprise buffering agents. Solid compositions of a similar type may also be employed as fillers in soft 5 and hard-filled gelatin capsules using such excipients as lactose or milk sugar as well as high molecular weight polyethylene glycols and the like. 'The solid dosage forms of tablets, dragees, capsules, pills, and granules can be prepared with coatings and shells such as enteric coatings and other coatings well known in the pharmaceutical formulating art. They may optionally contain 10 opacifying agents and can also be of a composition that they release the active ingredient(s) only, or preferentially, in a certain part of the intestinal tract, optionally, in a delayed manner. Examples of embedding compositions that can be used include polymeric substances and waxes. Dosage forms for topical or transdermal administration of a compound of 15 this invention include ointments, pastes, creams, lotions, gels, powders, solutions, sprays, inhalants or patches. The active component is admixed under sterile conditions with a pharmaceutically acceptable carrier and any needed preservatives or buffers as may be required. Ophthalmic formulation, ear drops, eye ointments, powders and solutions are also contemplated as being within the scope of this 20 invention. The ointments, pastes, creams and gels may contain, in addition to an active compound of this invention, excipients such as animal and vegetable fats, oils, waxes, paraffins, starch, tragacanth, cellulose derivatives, polyethylene glycols, silicones, bentonites, silicic acid, talc and zinc oxide, or mixtures thereof. 25 Powders and sprays can contain, in addition to the compounds of this invention, excipients such as lactose, talc, silicic acid, aluminum hydroxide, calcium silicates and polyamide powder, or mixtures of these substances. Sprays can additionally contain customary propellants such as chlorofluorohydrocarbons. Transdermal patches have the added advantage of providing controlled 30 delivery of a compound to the body. Such dosage forms can be made by dissolving or dispensing the compound in the proper medium. Absorption enhancers can also be used to increase the flux of the compound across the skin. The rate can be controlled by either providing a rate controlling membrane or by dispersing the compound in a polymer matrix or gel. 58 WO 2009/035718 PCT/US2008/056393 For pulmonary delivery, a therapeutic composition of the invention is formulated and administered to the patient in solid or liquid particulate form by direct administration e.g., inhalation into the respiratory system. Solid or liquid particulate forms of the active compound prepared for practicing the present 5 invention include particles of respirable size: that is, particles of a size sufficiently small to pass through the mouth and larynx upon inhalation and into the bronchi and alveoli of the lungs. Delivery of aerosolized therapeutics, particularly aerosolized antibiotics, is known in the art (see, for example U.S. Pat. No. 5,767,068 to VanDevanter et al., U.S. Pat. No. 5,508,269 to Smith et al., and WO 98/43,650 by 10 Montgomery, all of which are incorporated herein by reference). A discussion of pulmonary delivery of antibiotics is also found in U.S. Pat. No. 6,014,969, incorporated herein by reference. By a "therapeutically effective amount" of a compound of the invention is meant an amount of the compound which confers a therapeutic effect on the treated 15 subject, at a reasonable benefit/risk ratio applicable to any medical treatment. The therapeutic effect may be objective (i.e., measurable by some test or marker) or subjective (i.e., subject gives an indication of or feels an effect). An effective amount of the compound described above may range from about 0.1 mg/Kg to about 500 mg/Kg, preferably from about I to about 50 mg/Kg. Effective 20 doses will also vary depending on route of administration, as well as the possibility of co-usage with other agents. It will be understood, however, that the total daily usage of the compounds and compositions of the present invention will be decided by the attending physician within the scope of sound medical judgment. The specific therapeutically effective dose level for any particular patient will depend 25 upon a variety of factors including the disorder being treated and the severity of the disorder; the activity of the specific compound employed; the specific composition employed; the age, body weight, general health, sex and diet of the patient; the time of administration, route of administration, and rate of excretion of the specific compound employed; the duration of the treatment; drugs used in combination or 30 contemporaneously with the specific compound employed; and like factors well known in the medical arts. The total daily dose of the compounds of this invention administered to a human or other animal in single or in divided doses can be in amounts, for example, from 0.01 to 50 mg/kg body weight or more usually from 0.1 to 25 mg/kg body 59 WO 2009/035718 PCT/US2008/056393 weight. Single dose compositions may contain such amounts or submultiples thereof to make up the daily dose. In general, treatment regimens according to the present invention comprise administration to a patient in need of such treatment from about 10 mg to about 1000 mg of the compound(s) of this invention per day in 5 single or multiple doses. The salts or complexes of the formulae described herein can, for example, be administered by injection, intravenously, intraarterially, subdermally, intraperitoneally, intramuscularly, or subcutaneously; or orally, buccally, nasally, transmucosally, topically, in an ophthalmic preparation, or by inhalation, with a 10 dosage ranging from about 0.1 to about 500 mg/kg of body weight, alternatively dosages between 1 mg and 1000 mg/dose, every 4 to 120 hours, or according to the requirements of the particular drug. The methods herein contemplate administration of an effective amount of salt or pharmaceutical composition composition comprising the salt to achieve the desired or stated effect. Typically, the 15 pharmaceutical compositions of this invention will be administered from about I to about 6 times per day or alternatively, as a continuous infusion. Such administration can be used as a chronic or acute therapy. The amount of active ingredient that may be combined with pharmaceutically excipients or carriers to produce a single dosage form will vary depending upon the host treated and the particular mode of 20 administration. A typical preparation will contain from about 5% to about 95% active salt (w/w). Alternatively, such preparations may contain from about 20% to about 80% active salt. Lower or higher doses than those recited above may be required. Specific dosage and treatment regimens for any particular patient will depend upon a variety 25 of factors, including the activity of the specific compound employed, the age, body weight, general health status, sex, diet, time of administration, rate of excretion, drug combination, the severity and course of the disease, condition or symptoms, the patient's disposition to the disease, condition or symptoms, and the judgment of the treating physician. 30 Upon improvement of a patient's condition, a maintenance dose of a salt, composition or combination of this invention may be administered, if necessary. Subsequently, the dosage or frequency of administration, or both, may be reduced, as a function of the symptoms, to a level at which the improved condition is retained when the symptoms have been alleviated to the desired level. Patients may, 60 WO 2009/035718 PCT/US2008/056393 however, require intermittent treatment on a long-term basis upon any recurrence of disease symptoms. Synthetic Methods A quinazoline derivative of any of the formulae 1-IV, or a pharmaceutically 5 acceptable salt thereof, may be prepared by any process known to be applicable to the preparation of chemically-related compounds.
