Description

TITLE OF THE INVENTION AMINOPYRIMIDINES AS SYK INHIBITORS BACKGROUND OF THE INVENTION Spleen Tyrosine Kinase (Syk) is a protein tyrosine kinase which has been described as a key mediator of immunoreceptor signalling in a host of inflammatory cells including mast cells, B-cells, macrophages and neutrophils. These immunoreceptors, including Fe receptors and the B-cell receptor, are important for both allergic diseases and antibody mediated autoimmune diseases and thus pharmacologically interfering with Syk could conceivably treat these disorders. Allergic rhinitis and asthma are diseases associated with hypersensitivity reactions and inflammatory events involving a multitude of cell types including mast cells, eosinophils, T cells and dendritic cells. Following exposure to allergen, high affinity immunoglobulin receptors for IgE and IgG become cross-linked and activate downstream processes in mast cells and other cell types leading to the release of pro-inflammatory mediators and airway spasmogens. In the mast cell, for example, IgE receptor cross-linking by allergen leads to release of mediators including histamine from pre-formed granules, as well as the synthesis and release of newly synthesized lipid mediators including prostaglandins and leukotrienes. Syk kinase is a non-receptor linked tyrosine kinase which is important in transducing the downstream cellular signals associated with cross-linking Fe.epsilon.R1 and or Fc.epsilon.Rl receptors, and is positioned early in the signalling cascade. In mast cells, for example, the early sequence of Fc.epsilon.R1 signalling following allergen cross-linking of receptor-IgE complexes involves first Lyn (a Src family tyrosine kinase) and then Syk. Inhibitors of Syk activity would therefore be expected to inhibit all downstream signalling cascades thereby alleviating the immediate allergic response and adverse events initiated by the release of pro inflammatory mediators and spasmogens (Wong et al 2004, Expert Opin. Investig. Drugs (2004) 13 (7) 743-762). Recently, it has been shown that the Syk kinase inhibitor RI 12 (Rigel), dosed intranasally in a phase I/Il study for the treatment of allergic rhinitis, gave a statistically 0 significant decrease in PGD2, a key immune mediator that is highly correlated with improvements in allergic rhinorrhea, as well as being safe across a range of indicators, thus providing the first evidence for the clinical safety and efficacy of a topical Syk kinase inhibitor. (Meltzer, Eli 0.; Berkowitz, Robert B.; Grossbard, Elliott B, Journal of Allergy and Clinical Immunology (2005), 115(4), 791-796). In a more recent phase II clinical trial for allergic rhinitis 5 (Clinical Trials.gov Identifier NCTO0 15089), RI 12 was shown as having a lack of efficacy versus placebo. Rheumatoid Arthritis (RA) is an auto-immune disease affecting approximately 1% of the population. It is characterised by inflammation of articular joints leading to debilitating destruction of bone and cartilage. Recent clinical studies with Rituximab, which causes a reversible B cell depletion. (1. C. W. Edwards et aW 2004, New Fng, . Med. 350; 2572-2581) have shown that targeting B cel fnction is an appropriate therapeutic strategy in auto-immune diseases such as RA. Clinical benefit cwieictes with a reduction auto-reactive antibodies (or Rheumatoid Factr) and these studies suggest 1hat B cell function and indeed auto-antibody production are central to the o going pathology in the disease, Studies using celkl from mice deficient in the Spleen Tyrosine Kinase (Syk) have demonstrated a non-redundant role of this kinase in B cell function. The deficiency in Syk is chareterised by a block i B cell development (N. Turner et a 1995 Na t ure 379: 298-302 and Cheng et al 1995, Nature 378: 303-306). These studies, along with studies on mature B cells deficient in Syk (Kurasaki et al 2000, Irmnmolt Rev. 176:19-29), demonstrate that Syk is required for the differentiation and activation of B cells. Hence., inhibition of Syk in RA patients 10 s likely block B cel function and thereby reduce Rheumatoid Factor production. In addition to the role of Syk in B cell function, and of further relevance to the treatment of RA, is the requirement for Syk actvity in Freceptor (Fe.R) signalling. FcR activation by immune complexes in L has been suggested to contribute to the release of multiple pro-inflammnaory mediators. The present invention relates to novel compounds, which are inhibitors of Syk 15 kinase activity, These compounds therefore have potential therapeutic benefit in the treatment of disorders associated with inappropriate Syk activity, in particular in the treatment and prevention of disease states mediated by Syk Such disease states may include inflammatory, allergic and autinmmune diseases, for example. asthra, chronic obstructive puhmonary disease (COPD), adult respiratory distress syndrome (ARtDS) ulcerative colitis, Crobas disease, hronchitis, dermatitis, allergic rhinitis, psoriasis, sclerodenna, urticaria, rhewuatoid arthritis, idiopathic thmmnbocytopenic purpura (IT?), muliple sclerosis, cancer, lIV and lupus. 20 SUMMARY OF THE INVENTION The present invention provides novel compounds that are potent inhibitors of SYK as well as phannaceutical compositions containing them.

The term "composition", as in pharmaceutical composition, is intended to encompass a product comprising the active ingredient(s), and the inert ingredient(s) (pharmaceutically acceptable excipients) that make up the carrier, as well as any product which results, directly or indirectly, from combination, complexation or aggregation of any two or more of the ingredients, or from dissociation of one or more of the ingredients, or from other types of reactions or interactions of one or more of the ingredients. Accordingly, the pharmaceutical compositions of the present invention encompass any composition made by admixing a compound of formula I, and pharmaceutically acceptable excipients. As used herein, the term "optionally" means that the subsequently described event(s) may or may not occur, and includes both event(s), which occur, and events that do not occur. 0 As used herein, the term "substituted with one or more groups" refers to substitution with the named substituent or substituents, multiple degrees of substitution, up to replacing all hydrogen atoms with the same or different substituents, being allowed unless the number of substituents is explicitly stated. Where the number of substituents is not explicitly stated, one or more is intended. 5 Each variable is independently defined each time it occurs within the generic structural formula definitions. For example, when there is more than one Rz(a) substituents on the Cy ring, each substituent is independently selected at each occurrence, and each substituent can be the same or different from the other(s). As another example, for the group NRa(a)Ra(a), each occurrence of the two Ra(a) groups may be the same or different.

As used herein, where the notation "Co" or "(CH2)0" modifies a substituent, it indicates a bond between the substituent and the rest of the molecule. Thus, the term "Cq-3alkyl CO2H" means the carboxy group is either directly attached to the rest of the molecule, or there is an intervening C1I-3alkyl group therebetween. The term "Syk inhibitor", is used to mean a compound which inhibits the Syk enzyme. The term "Syk mediated disease" or a "disorder or disease or condition mediated by inappropriate Syk activity" is used to mean any disease state mediated or modulated by Syk kinase mechanisms. Such disease states may include inflammatory, allergic and autoimmune diseases, for example, asthma, chronic obstructive pulmonary disease (COPD), adult respiratory distress syndrome (ARDs), ulcerative colitis, Crohns disease, bronchitis, dermatitis, allergic rhinitis, psorasis, scleroderma, urticaria, rheumatoid arthritis, multiple sclerosis, cancer, HIV and lupus, in particular, asthma, chronic obstructive pulmonary disease (COPD), adult respiratory distress syndrome (ARDs), allergic rhinitis and rheumatoid arthritis. As used herein, "a compound of the invention" means a compound of formula (J) or a salt, solvate or physiologically functional derivative thereof. As used herein, the term solvatee" refers to a complex of variable stoichiometry formed by a solute (in this invention, a compound of formula (I), or a salt thereof) and a solvent. Such solvents for the purpose of the invention may not interfere with the biological activity of the solute. Examples of suitable solvents include, but are not limited to, water, acetone, methanol, ethanol and acetic acid. Preferably the solvent used is a pharmaceutically acceptable solvent. Examples of suitable pharmaceutically acceptable solvents include water, ethanol and acetic acid. Most preferably the solvent is water. As used herein, the term "physiologically functional derivative" refers to a > compound (e.g, a drug precursor) that is transformed in vivo to yield a compound of Formula (I) or a pharmaceutically acceptable salt, hydrate or solvate of the compound. The transformation may occur by various mechanisms (e.g., by metabolic or chemical processes), such as, for example, through hydrolysis in blood. Prodrugs are such derivatives, and a discussion of the use of prodrugs is provided by T. Higuchi and W. Stella, "Pro-drugs as Novel Delivery Systems," D Vol. 14 of the A.C.S. Symposium Series, and in Bioreversible Carriers in Drug Design, ed. Edward B. Roche, American Pharmaceutical Association and Pergamon Press, 1987. The compounds of formula (1) may have the ability to crystallize in more than one form, a characteristic known as polymorphism, and it is understood that such polymorphic forms polymorphshs") are within the scope of formula (1). Polymorphism generally can occur as a 5 response to changes in temperature or pressure or both and can also result from variations in the crystallization process. Polymorphs can be distinguished by various physical characteristics known in the art such as x-ray diffraction patterns, solubility and melting point. The compounds of Formula (I) may contain asymmetric or chiral centers, and, therefore, exist in different stereoisomeric forms. It is intended that all stereoisomeric forms of the compounds of Formula (I) as well as mixtures thereof, including racemic mixtures, form part of the present invention. Diastereomeric mixtures can be separated into their individual diastereomers on the basis of their physical chemical differences by methods well known to those skilled in the art, such as, for example, by chromatography and/or fractional crystallization. Enantiomers can be separated by converting the enantiomeric mixture into a diastereomeric mixture by reaction with an appropriate optically active compound (e.g., chiral auxiliary such as a chiral alcohol or Mosher's acid chloride), separating the diastereomers and converting (e.g., hydrolyzing) the individual diastereomers to the corresponding pure enantiomers. Also, some of the compounds of Formula (I) may be atropisomers (e.g., substituted biaryls) and are considered as part of this invention. It is also noted that the compounds of Formula (I) may form tautomers. It is understood that all tautomers and mixtures of tautomers of the compounds of the present invention are included within the scope of the compounds of the present invention. Some of the compounds described herein contain olefinic double bonds, and unless specified otherwise, are meant to include both E and Z geometric isomers. Whilst the embodiments for each variable have generally been listed above separately for each variable, this invention also includes those compounds in which several or each embodiment in formula (I) is selected from each of the embodiments listed above. Therefore, this invention is intended to include all combinations of embodiments for each variable. The compounds of the present invention may be in the form of and/or may be administered as a pharmaceutically acceptable salt. For a review on suitable salts see Berge et al, J. Pharm. Sci. 1977, 66, 1-19. Typically, the salts of the present invention are pharmaceutically acceptable salts. Salts encompassed within the term "pharmaceutically acceptable salts" refer to non-toxic salts of the compounds of this invention.

The invention thus provides compounds of formula (I) and salts, solvates and physiologically functional derivatives thereof for use in therapy, and particularly in the treatment of diseases and conditions mediated by inappropriate Syk activity. The inappropriate Syk activity referred to herein is any Syk activity that deviates from the normal Syk activity expected in a particular mammalian subject. Inappropriate Syk activity may take the form of, for instance, an abnormal increase in activity, or an aberration in the timing and or control of Syk activity. ) Such inappropriate activity may result then, for example, from overexpression or mutation of the protein kinase leading to inappropriate or uncontrolled activation. In a further embodiment, the present invention is directed to methods of regulating, modulating, or inhibiting Syk for the prevention and/or treatment of disorders related to unregulated Syk activity. In a further embodiment, the present invention provides a method of treatment of a mammal suffering from a disorder mediated by Syk activity, which comprises administering to said mammal an effective amount of a compound of formula (1) or a pharmaceutically acceptable salt, solvate, or a physiologically functional derivative thereof In a further embodiment, the present invention provides for the use of a compound of formula (I), or a pharmaceutically acceptable salt or solvate thereof, or a physiologically functional derivative thereof, in the preparation of a medicament for the treatment of a disorder mediated by Syk activity. In a further embodiment said disorder mediated by Syk activity is asthma. In a further embodiment said disorder is rheumatoid arthritis. In yet another embodiment, said disorder is cancer. In a further embodiment said disorder is ocular conjunctivitis. Yet another aspect of the present invention provides a method for treating diseases caused by or associated with Fc receptor signaling cascades, including FceRI and/or FcgRI mediated degranulation as a therapeutic approach towards the treatment or prevention of diseases characterized by, caused by and/or associated with the release or synthesis of chemical mediators of such Fc receptor signaling cascades or degranulation. In addition, Syk is known to play a critical role in immunotyrosine-based activation motif (ITAM) singaling, B cell receptor signaling, T cell receptor singaling and is an essential component of integrin beta (1), beta (2), and beta (3) signaling in neutrophils. Thus, compounds of the present invention can be used to regulate Fc receptor, ITAM, B cell receptor and integrin singaling cascades, as well as the cellular responses elicited through these signaling cascades. Non-limiting examples of cellular resonses that may be regulated or inhibited include respiratory burst, cellular adhesion, cellular degranulation, cell spreading, cell migration, phagocytosis, calcium ion flux, platelet aggregation and cell maturation. While it is possible that, for use in therapy, a compound of formula (I), as well as salts, solvates and physiological functional derivatives thereof, may be administered as the raw chemical, it is possible to present the active ingredient as a pharmaceutical composition. Accordingly, the invention further provides a pharmaceutical composition, which comprises a compound of formula (I) and salts, solvates and physiological functional derivatives thereof, and. one or more pharmaceutically acceptable carriers, diluents, or excipients. The compounds of the formula (I) and salts, solvates and physiological functional derivatives thereof, are as described above. The carrier(s), diluent(s) or excipient(s) must be acceptable in the sense of being compatible with the other ingredients of the formulation and not deleterious to the recipient thereof. In accordance with another aspect of the invention there is also provided a process for 0 the preparation of a pharmaceutical composition including admixing a compound of the formula (I), or salts, solvates and physiological functional derivatives thereof, with one or more pharmaceutically acceptable carriers, diluents or excipients. Pharmaceutical compositions of the present invention may be presented in unit dose forms containing a predetermined amount of active ingredient per unit dose. Such a unit 5 may contain, for example, 5pg to I g, preferably I mg to 700 mg, more preferably 5 mg to 100 mg of a compound of the formula (I), depending on the condition being treated, the route of administration and the age, weight and condition of the patient. Such unit doses may therefore be administered more than once a day. Preferred unit dosage compositions are those containing a daily dose or sub-dose (for administration more than once a day), as herein above recited, or an appropriate fraction thereof, of an active ingredient. Furthermore, such pharmaceutical compositions may be prepared by any of the methods well known in the pharmacy art. Pharmaceutical compositions of the present invention may be adapted for administration by any appropriate route, for example by the oral (including buccal or sublingual), rectal, topical, inhaled, nasal, ocular, or parenteral (including intravenous and intramuscular) route. Such compositions may be prepared by any method known in the art of pharmacy, for example by bringing into association the active ingredient with the carrier(s) or excipient(s). Dosage forms include tablets, troches, dispersions, suspensions, solutions, capsules, creams, ointments, aerosols, and the like. In a further embodiment, the present invention provides a pharmaceutical composition adapted for administration by the oral route, for treating, for example, rheumatoid arthritis. In a further embodiment, the present invention provides a pharmaceutical composition adapted for administration by the nasal route, for treating, for example, allergic rhinitis. In a further embodiment, the present invention provides a pharmaceutical composition adapted for administration by the inhaled route, for treating, for example, asthma, COPD or ARDS. In a further embodiment, the present invention provides a pharmaceutical composition adapted for administration by the ocular route, for treating, diseases of the eye, for example, conjunctivitis. In a further embodiment, the present invention provides a pharmaceutical composition adapted for administration by the parenteral (including intravenous) route, for treating, for example, cancer. > Pharmaceutical compositions of the present invention which are adapted for oral administration may be presented as discrete units such as capsules or tablets; powders or granules; solutions or suspensions in aqueous or non-aqueous liquids; edible foams or whips; or oil-in-water liquid emulsions or water-in-oil liquid emulsions. For instance, for oral administration in the form of a tablet or capsule, the active D drug component can be combined with an oral, non-toxic pharmaceutically acceptable inert carrier such as ethanol, glycerol, water and the like. Powders are prepared by comminuting the compound to a suitable fine size and mixing with a similarly comminuted pharmaceutical carrier such as an edible carbohydrate, as, for example, starch or mannitol. Flavoring, preservative, dispersing and coloring agent can also be present. 5 Capsules are made by preparing a powder mixture, as described above, and filling formed gelatin sheaths. Glidants and lubricants such as colloidal silica, tale, magnesium stearate, calcium stearate or solid polyethylene glycol can be added to the powder mixture before the filling operation. A disintegrating or solubilizing agent such as agar-agar, calcium carbonate or sodium carbonate can also be added to improve the availability of the medicament when the capsule is ingested. Moreover, when desired or necessary, suitable binders, lubricants, disintegrating agents and coloring agents can also be incorporated into the mixture. Suitable binders include starch, gelatin, natural sugars such as glucose or beta-lactose, corn sweeteners, natural and synthetic gums such as acacia, tragacanth or sodium alginate, carboxymethyleellulose, polyethylene glycol, waxes and the like. Lubricants used in these dosage forms include sodium oleate, sodium stearate, magnesium stearate, sodium benzoate, sodium acetate, sodium chloride and the like. Disintegrators include, without limitation, starch, methyl cellulose, agar, bentonite, xanthan gum and the like. Tablets are formulated, for example, by preparing a powder mixture, granulating or slugging, adding a lubricant and disintegrant and pressing into tablets. A powder mixture is prepared by mixing the compound, suitably comminuted, with a diluent or base as described above, and optionally, with a binder such as carboxymethyleellulose, an aliginate, gelatin, or polyvinyl pyrrolidone, a solution retardant such as paraffin, a resorption accelerator such as a quaternary salt and/or an absorption agent such as bentonite, kaolin or dicalcium phosphate. The powder mixture can be granulated by wetting with a binder such as syrup, starch paste, acadia mucilage or solutions of cellulosic or polymeric materials and forcing through a screen. As an alternative to granulating, the powder mixture can be run through the tablet machine and the result is imperfectly formed slugs broken into granules. The granules can be lubricated to prevent sticking to the tablet forming dies by means of the addition of stearic acid, a stearate salt, talc or mineral oil. The lubricated mixture is then compressed into tablets. The compounds of the present invention can also be combined with a free flowing inert carrier and compressed into tablets directly without going through the granulating or slugging steps. A clear or opaque protective coating consisting of a sealing coat of shellac, a coating of sugar or polymeric material and a polish coating of wax can be provided. Dyestuffs can be added to these 5 coatings to distinguish different unit dosages. Oral fluids such as solution, syrups and elixirs can be prepared in dosage unit form so that a given quantity contains a predetermined amount of the compound. Syrups can be prepared by dissolving the compound in a suitably flavored aqueous solution, while elixirs are prepared through the use of a non-toxic alcoholic vehicle. Suspensions can be formulated by 0 dispersing the compound in a non-toxic vehicle. Solubilizers and emulsifiers such as ethoxylated isostearyl alcohols and polyoxy ethylene sorbitol ethers, preservatives, flavor additive such as peppermint oil or natural sweeteners or saccharin or other artificial sweeteners, and the like can also be added. Where appropriate, dosage unit compositions for oral administration can be 5 microencapsulated. The formulation can also be prepared to prolong or sustain the release, for example, by coating or embedding particulate material in polymers, wax or the like. The compounds of formula (I), and salts, solvates and physiological functional derivatives thereof, can also be administered in the form of liposome delivery systems, such as small unilamellar vesicles, large unilamellar vesicles and multilamellar vesicles. Liposomes can be formed from a variety of phospholipids, such as cholesterol, stearylamine or phosphatidylcholines. The compounds of formula (I) and salts, solvates and physiological functional derivatives thereof may also be delivered by the use of monoclonal antibodies as individual carriers to which the compound molecules are coupled. The compounds may also be coupled with soluble polymers as targetable drug carriers. Such polymers can include polyvinylpyrrolidone, pyran copolymer, polyhydroxypropylmethacrylamide-phenol, polyhydroxyethylaspartamidephenol, or polyethyleneoxidepolylysine substituted with palmitoyl residues. Furthermore, the compounds may be coupled to a class of biodegradable polymers useful in achieving controlled release of a drug, for example, polylactic acid, polyepsilon caprolactone, polyhydroxy butyric acid, polyorthoesters, polyacetals, polydihydropyrans, polycyanoacrylates and cross-linked or amphipathic block copolymers of hydrogels. Dosage forms for inhaled administration may conveniently be formulated as aerosols or dry powders. For compositions suitable and/or adapted for inhaled administration, it is preferred that the compound or salt of formula (I) is in a particle-size-reduced form, and more preferably the size-reduced form is obtained or obtainable by micronisation. The preferable particle size of the size-reduced (e.g. micronised) compound or salt or solvate is defined by a D50 value of about 0.5 to about 10 microns (for example as measured using laser diffraction). Aerosol formulations, e.g. for inhaled administration, can comprise a solution or fine suspension of the active substance in a pharmaceutically acceptable aqueous or non-aqueous solvent. Aerosol formulations can be presented in single or multidose quantities in sterile form in a sealed container, which can take the form of a cartridge or refill for use with an atomising device or inhaler. Alternatively the sealed container may be a unitary dispensing device such as a 5 single dose nasal inhaler or an aerosol dispenser fitted with a metering valve (metered dose inhaler) which is intended for disposal once the contents of the container have been exhausted. Where the dosage form comprises an aerosol dispenser, it preferably contains a suitable propellant under pressure such as compressed air, carbon dioxide or an organic propellant such as a hydrofluorocarbon (HFC). Suitable HFC propellants include 1,1,1,2,3,3,3 0 heptafluoropropane and 1,1,1,2-tetrafluoroethane. The aerosol dosage forms can also take the form of a pump-atomiser. The pressurised aerosol may contain a solution or a suspension of the active compound. This may require the incorporation of additional excipients e.g. co-solvents and/or surfactants to improve the dispersion characteristics and homogeneity of suspension formulations. Solution formulations may also require the addition of co-solvents such as ethanol. 5 Other excipient modifiers may also be incorporated to improve, for example, the stability and/or taste and/or fine particle mass characteristics (amount and/or profile) of the formulation. For pharmaceutical compositions suitable and/or adapted for inhaled administration, it is preferred that the pharmaceutical composition is a dry powder inhalable composition. Such a composition can comprise a powder base such as lactose, glucose, trehalose, mannitol or starch, the compound of formula (I) or salt or solvate thereof (preferably in particle size-reduced form, e.g. in micronised form), and optionally a performance modifier such as L leucine or another amino acid, and/or metals salts of stearic acid such as magnesium or calcium stearate. Preferably, the dry powder inhalable composition comprises a dry powder blend of lactose and the compound of formula (I) or salt thereof. The lactose is preferably lactose hydrate e.g. lactose monohydrate and/or is preferably inhalation-grade and/or fine-grade lactose. Preferably, the particle size of the lactose is defined by 90% or more (by weight or by volume) of the lactose particles being less than 1000 microns (micrometres) (e.g. 10-1000 microns e.g. 30 1000 microns) in diameter, and/or 50% or more of the lactose particles being less than 500 microns (e.g. 10-500 microns) in diameter. More preferably, the particle size of the lactose is defined by 90% or more of the lactose particles being less than 300 microns (e.g. 10-300 microns e.g. 50-300 microns) in diameter, and/or 50% or more of the lactose particles being less than 100 microns in diameter. Optionally, the particle size of the lactose is defined by 90% or more of the lactose particles being less than 100-200 microns in diameter, and/or 50% or more of the lactose particles being less than 40-70 microns in diameter. It is preferable that about 3 to about 30% (e.g. about 10%) (by weight or by volume) of the particles are less than 50 microns or less than 20 microns in diameter. For example, without limitation, a suitable inhalation-grade lactose is E9334 lactose (10% fines) (Borculo Domo Ingredients, Hanzeplein 25, 8017 J D Zwolle, Netherlands). Optionally, in particular for dry powder inhalable compositions, a pharmaceutical composition for inhaled administration can be incorporated into a plurality of sealed dose containers (e.g. containing the dry powder composition) mounted longitudinally in a strip or ribbon inside a suitable inhalation device. The container is rupturable or peel-openable on demand and the dose of e.g. the dry powder composition can be administered by inhalation via 5 the device such as the DISKUS@ device(GlaxoSmithKline). Other dry powder inhalers are well known to those of ordinary skill in the art, and many such devices are commercially available, with representative devices including Aerolizert (Novartis), AirmaxTM (IVAX), ClickHaler@ (Innovata Biomed), Diskhaler@ (GlaxoSmithKline), Accuhaler (GlaxoSmithKline), Easyhaler@ (Orion Pharma), EclipseTM (Aventis), FlowCaps@ (Hovione), Handihaler@ (Boehringer 0 Ingelheim), Pulvinal@ (Chiesi), Rotahaler@ (GlaxoSmithKline), SkyeHaler T M or CertihalerTM (SkyePharma), Twisthaler (Schering-Plough), Turbuhaler@ (AstraZeneca), Ultrahaler@ (Aventis), and the like. Dosage forms for ocular administration may be formulated as solutions or suspensions with excipients suitable for ophthalmic use. 5 Dosage forms for nasal administration may conveniently be formulated as aerosols, solutions, drops, gels or dry powders. Pharmaceutical compositions adapted for administration by inhalation include fine particle dusts or mists, which may be generated by means of various types of metered, dose pressurised aerosols, nebulizers or insufflators.

For pharmaceutical compositions suitable and/or adapted for intranasal administration, the compound of formula (I) or a pharmaceutically acceptable salt or solvate thereof may be formulated as a fluid formulation for delivery from a fluid dispenser. Such fluid dispensers may have, for example, a dispensing nozzle or dispensing orifice through which a metered dose of the fluid formulation is dispensed upon the application of a user-applied force to a pump mechanism of the fluid dispenser. Such fluid dispensers are generally provided with a reservoir of multiple metered doses of the fluid formulation, the doses being dispensable upon sequential pump actuations. The dispensing nozzle or orifice may be configured for insertion into the nostrils of the user for spray dispensing of the fluid formulation into the nasal cavity. A fluid dispenser of the aforementioned type is described and illustrated in WO-A-2005/044354, the entire content of which is hereby incorporated herein by reference. The dispenser has a housing which houses a fluid discharge device having a compression pump mounted on a container for containing a fluid formulation. The housing has at least one finger-operable side lever which is movable inwardly with respect to the housing to cam the container upwardly in the housing to cause the pump to compress and pump a metered dose of the formulation out of a pump stem through a nasal nozzle of the housing. A particularly preferred fluid dispenser is of the general type illustrated in FIGS. 30-40 of WO-A-2005/044354.

It will be clear to a person skilled in the art that, where appropriate, the other therapeutic ingredient(s) may be used in the form of salts, for example as alkali metal or amine salts or as acid addition salts, or prodrugs, or as esters, for example lower alkyl esters, or as solvates, for example hydrates, to optimise the activity and/or stability and/or physical characteristics, such as solubility, of the therapeutic ingredient. It will be clear also that, where appropriate, the therapeutic ingredients may be used in optically pure form. The combinations referred to above may conveniently be presented for use in the form of a pharmaceutical composition and thus pharmaceutical compositions comprising a combination as defined above together with a pharmaceutically acceptable diluent or carrier represent a further aspect of the invention. These combinations are of particular interest in respiratory diseases and are conveniently adapted for inhaled or intranasal delivery. The individual compounds of such combinations may be administered either sequentially or simultaneously in separate or combined pharmaceutical compositions. Preferably, 5 the individual compounds will be administered simultaneously in a combined pharmaceutical composition. Appropriate doses of known therapeutic agents will be readily appreciated by those skilled in the art. The compounds of this invention may be made by a variety of methods, including standard chemistry. Any previously defined variable will continue to have the previously defined 0 meaning unless otherwise indicated. Illustrative general synthetic methods are set out below and then specific compounds of the invention are prepared in the Examples.

In all of the schemes described below, it is well understood that protecting groups for sensitive or reactive groups are 5 employed where necessary in accordance with general principles of chemistry. Protecting groups are manipulated according to standard methods of organic synthesis (T. W. Green and P. G. M. Wuts (1991) Protecting Groups in Organic Synthesis, John Wiley & Sons). These groups are removed at a convenient stage of the compound synthesis using methods that are readily apparent to those skilled in the art. The selection of protecting groups as well as the reaction conditions and order of reaction steps shall be consistent with the preparation of compounds of Formula (I). Those skilled in the art will recognize if a stereocenter exists in compounds of Formula (I). Accordingly, the present invention includes all possible stereoisomers and includes not only mixtures of stercoisomers (such as racemic compounds) but the individual stereoisomers as well. When a compound is desired as a single enantiomer, it may be obtained by stereospecific synthesis or by resolution of the final product or any convenient intermediate. Resolution of the final product, an intermediate, or a starting material may be effected by any suitable method known in the art. See, for example, Stereochemistry of Organic Compounds by E. L. Eliel, S. H. Wilen, and L. N. Mander (Wiley-Interscience, 1994).

Thiazole (53.2 mL, 749 mmol) was added over 15 minutes, resulting in an orange/red solution. Stirred for 20 min at 0 OC, then removed cooling bath and allowed to warm to rt. Stirred an additional 2 h, then recooled to 0 OC. Cyclobutanone (53.3 mL, 713 mmol) was added over 50 min. Removed the cooling bath and allowed to warm to rt and stirred 20 min at that temperature. The reaction mixture was cooled to 0 OC and saturated aqueous ammonium chloride was slowly added. The mixture was diluted with EtOAc, the layers separated and the organic portion washed with water. The aqueous layer was washed with ethyl acetate. The combined organic portions were dried over MgSO4 and concentrated in vacuo to provide 127.5 g of material containing 1-(1,3-thiazol-2-yl)cyclobutanol, which was used without further purification. Step 2: The product of Step 1 (171.9 g, 1.107 mol) was dissolved in DMF (860 mL) and cooled 5 to 0 OC. Added NBS (236 g, 1.327 mol) and stirred 1 h at 0 OC.

2 OH 5 Step 1: To a stirred solution of 1,5-dihydroxypentan-3-one (300 mg, 2.54 mmol) in DMF (12.7 mL) was added imidazole (864 mg, 12.7 mmol), followed by TBDMSCl (919 mg, 6.09 mmol). The reaction mixture was stirred overnight at room temperature. Another portion of imidazole (864 mg, 12.7 mmol) and TBDMSCI (919 mg, 6.09 mmol) were added to the solution and the reaction mixture was stirred 24 h. The reaction was quenched with sat. NaHCO3 and the 0 aqueous layer was extracted with Et20 (x 3). The combined organics were washed with brine, dried (Na2SO4) and concentrated after filtration. The residue was purified by flash chromatography to give 2,2,3,3,11,11,12,12-octamethyl-4,10-dioxa-3,1 1-disilatridecan-7-one (795 mg, 2.293 mmol, 90 % yield) as a colorless oil. Step 2: n-Butyl lithium (0.372 mL, 0.931 mmol)-was added to a stirred, cooled 0 'C mixture of 5 diisopropylamine (0.139 mL, 0.977 mmol) in THF (1.55 mL) and the mixture was stirred at 0 *C for 30 min and then cooled to -78 'C. To the cooled -78 *C LDA solution was added a solution of INTERMEDIATE 7 (100 mg, 0.310 mmol) in THF (1 mL) and the reaction mixture was stirred at that temperature for 30 minutes. At -78 'C was then added the product of Step 1 (323 mg, 0.931 mmol) and the reaction mixture was stirred overnight (temperature was allowed to reach slowly to room temperature). The reaction mixture was filtered through a pre-packed celite pad with DCM and the filtrate was concentrated. The residue was purified by flash chromatography to give 2,2,3,3,11,11,12,12-octamethyl-7- [5 -(3- { [4-(trifluoromethyl)pyrimidin 2-yl]amino)phenyl)-1,3-thiazol-2-yl]-4,10-dioxa-3,1 1-disilatridecan-7-ol (323 mg, 0.931 mmol) as a yellow oil.

3 N CF3 N N N 0 H H Step 1: Ammonium chloride (5.20 g, 97 mmol) was added to a stirred, cooled (room temperature) mixture of 1-bromo-3,5-dinitrobenzene (20 g, 81 mmol) and iron (54.3 g, 972 mmol) in ethanol:water (2:1) and the mixture was stirred at 80 'C for 1 h. The heterogeneous reaction was filtered on celite while hot, concentrated, and diluted with brine. The product was extracted with ethyl acetate, the organic layer washed with brine and dried over Na2SO4. The residue was dissolved in boiling ethyl acetate (-75 mL), a bit of hexanes was added to form a layer on top of ethyl acetate (- 7.5 mL) and the mixture was left to crystallize overnight. The crystals were filtered, washed with diethyl ether and air-dried to give 5.77g of 5-bromobenzene 1,3-diamine as a grey solid. MS ESI: [M + H]+ m/z 187.0 and 189.0. Step 2: Trifluoroacetic acid was added to a stirred, cooled (0 *C) mixture of the bromobenzene 1,3-diamine (3.00 g, 16.0 mmol) and sodium cyanoborohydride (2.02 g, 32.1 mmol) in dichloromethane (note: gas evolution) at 0 'C. Then, trifluoroacetaldehyde (2.79 g, 24.06 mmol) was added and the mixture was stirred at room temperature for 45 min. The mixture was cooled to 0 *C, aqueous sodium carbonate (2M) was added until basic pH was achieved and no more gas evolution was observed then the mixture was extracted with ethyl acetate. The combined organic fractions were washed with brine, dried over Na2SO4, filtered and the solvent was evaporated under reduced pressure. The residue was purified by chromatography on silica gel (0-70% ethyl acetate in hexanes) to give 5-bromo-N-(2,2,2-trifluoroethyl)benzene-1,3-dianine (1.51 g, 5.61 mmol, 35 % yield) as a yellow oil that crystallized upon standing.

The mixture was heated to 85 'C and stirred overnight. LCMS analysis indicated incomplete reaction, and thus the mixture was cooled down to room temperature, diluted with diethyl ether and filtered on celite and the solvent was evaporated under reduced pressure. This impure material was redissolved in dioxane (3.0 mL) and additional bis(pinacolato)diboron (244 mg, 0.960 mnmol), potassium acetate (353 mg, 3.60 mmol), Pd2dba3 5 (27.5 mg, 0.030 mmol) and 2-dicyclohexylphosphino-2',4',6'-tri-isopropyl-1,1'-biphenyl (57.2 mg, 0.120 mmol) were added. The septum was replaced with a screwcap and the mixture stirred at 110 OC for 30 min. The mixture was cooled, Et2O and hexanes were added, and then was filtered on celite and washed with Et20. The volatiles were removed under partial vacuum, and the residue was then triturated in hexanes.

After cooling to room temperature, a NaOH solution (3 M, 5.00 mL, 15.0 mmol), which had been degassed by bubbling N2 for 15 minutes, was added and stirring was continued for an additional 2 hours. The resulting solution was used directly (-0.5 M) in the next step without further manipulation. Step 2: To a mixture of 2-[5-(3-bromo-5-([4-(trifluoromethyl)pyrimidin-2-yljamino}phenyl) 1,3-thiazol-2-yl]propan-2-ol (Example 4A-4, 50 mg, 0.109 mmol) and tetrakis(triphenylphosphine)palladium(0) (13 mg, 11 ptmol) was added the sodium (cyclooctane 1,5-diyl-c 2 CI,C5)(cyclopropyl)hydroxyborate(1-) solution (0.5 M, 650 pL, 0.327 mmol) from Step 1, and the mixture was heated to 75 'C overnight. The mixture was diluted with ethyl acetate (100 mL), dried (Na2SO4) and filtered through celite. After in vacuo concentration, purification by chromatography on silica gel (80:20 to 30:70 hexanes:Ethyl acetate over 20 minutes) provided the desired product contaminated by a minor by-product (-10%). Further purification by prep LCMS (50-90% CH3CN in NH4CO3(aq)) provided 15 mg (0.036 mmol, 33%) of 2- [5-(3 -cyclopropyl-5- {[4-(trifluoromethyl)pyrimidin-2-yl] amino} phenyl)- 1,3-thiazol-2 yl]propan-2-ol as a white solid.

Step 2: To a solution of the product from Step 1 (41.3 mg, 0.084 mmol) in tetrahydrofuran (0.4 mL) and methanol (0.8 mL) was added sodium hydroxide (1 M in water, 0.153 mL, 0.153 mmol). The reaction mixture was heated to 120 *C for 10 minutes in a microwave oven. An additional charge of sodium hydroxide was added (1 M in water, 0.300 mL, 0.300 mmol) and the vessel was heated again for 10 minutes at 120 *C. Upon cooling aqueous hydrogen chloride (2M in water, 0.235 mL, 0.470 umol) was added and the resulting mixture was diluted with 10% v/v isopropanol/chloroform (20 mL), brine (10 mL), and water (1 mL). The layers were separated and the aqueous layer was re-extracted with 10% v/v isopropanol/chloroform (10 mL). The organic layers were combined, dried over sodium sulfate, filtered, and concentrated. Lyophilization of the residue from methanol/water provided (1S, 4R)-4-(5-{3-cyclopropyl-5-[(4 methylpyrimidin-2-yl)amino]phenyl}-1,3-thiazol-2-yl)-4-hydroxy-2,2 dimethylcyclohexanecarboxylic acid (34.3 mg, 0.072 mmol, 84% yield) as an off-white solid.

3 N N N CH 3 H Step 1: To a stirred solution of (S)-(-)-2-methyl-2-propanesulfinamide (854 mg, 7 mmol) and 1,4-dioxaspiro[4,5]decan-8-one (1 g, 6.40 mmol) in tetrahydrofuran (13 mL) was added titanium(IV) ethoxide (5.11 mL, 16 mmol). The mixture was stirred for 4 h at room temperature, poured over stirring saturated aqueous sodium bicarbonate (10 mL) and acetonitrile (10 mL), and stirred for 20 minutes. Magnesium sulfate was added and the mixture was stirred for 20 minutes, filtered over celite and concentrated. The residue was purified by column chromatography on silica gel (10:90 to 70:30 ethyl acetate:hexanes gradient) to afford N-(1,4-dioxaspiro[4.5]dec-8 ylidene)-2-methylpropane-2-sulfinamide (466 mg, 1.8 mmol, 28% yield) as a white solid. MS ESI: [M+H]+ m/z 260. Step 2: To diisopropyl amine (318 piL, 2.23 mmol) in tetrahydrofuran (3.7 mL) at 0 'C was added N-butyllithium (2.5 M in hexanes, 892 p.L, 2.23 mmol). The mixture was stirred for 15 minutes, then cooled to -78 'C. INTERMEDIATE 4 (250 mg, 0.74 mmol) dissolved in tetrahydrofuran (1 mL) was added dropwise over 5 minutes. The mixture was stirred for 30 minutes at -78 *C, then the product of Step 1 (212 mg, 0.82 mmol) dissolved in tetrahydrofuran (1 mL) was added dropwise. The reaction mixture was stirred for 2 h, and then quenched with saturated aqueous ammonium chloride, extracted with ethyl acetate (3x), and the combined organic fractions were dried over sodium sulfate, filtered, and concentrated. Purification by column chromatography on silica gel (0:100 to 80:20 ethyl acetate:hexanes gradient, then 0:100 0 to 15:85 methanol:dichloromethane gradient) afforded 2-methyl-N-{8-[5-(3-methyl-5-{[4 (trifluoromethyl)pyrimidin-2-yl] amino} phenyl)- 1,3 -thiazol-2-yl]- 1,4-dioxaspiro[4.5] dec-8 yl}propane-2-sulfinamide (318 mg, 0.40 mmol, 75% yield) as a brown solid.

The mixture was heated to 65 *C for 1.5 h., cooled to room temperature, diluted with water, and extracted with ethyl acetate (2x). The combined organic layers were dried over sodium sulfate, filtered, and concentrated. The residue was purified by reverse phase HPLC (35:65 to 70:30 acetonitrile:water with a 0.1% trifluoroacetic acid modifier). The fractions containing the desired product were diluted with ethyl acetate and free based with saturated aqueous sodium bicarbonate. The separated organic layer was dried over magnesium sulfate, filtered and concentrated to afford the title compound (38 mg, 0.083 mmol, 66 % yield) as an orange oil.

The recombinant human GST SYK (Carna Biosciences #08-176) (5pM final concentration) was incubated with various concentrations of the inhibitor diluted in DMSO (0.1% final concentration) for 10 minutes at room temperature in 15 mM Tris-HCl (pH 7.5), 0.01% tween 20, 2 mM DTT in 384 well plate format. To initiate the reaction the biotinylated substrate peptide (250 nM final concentration) that contains the phosphorylation site for SYK was added with magnesium (5 mM final concentration) and ATP (25 gM final concentration). Final volume of the reaction was 10 L. Phosphorylation of the peptide was allowed to proceed for 45' at room temperature. To quench the reaction and detect the phosphorylated product, 2 nM of a Europium-anti-phosphotyrosine antibody (Perkin Elmer #ADO161) and 70 nM SA-APC (Perkin-Elmer #CR130-100) were added together in 15 mM Tris pH 7.5,40 mM EDTA, 0.01% tween 20. Final volume of the quenching solution was 10 L. The resulting HTRF signal was measured after 30 minutes on a EnVision (Perkin-Elmer) reader using a time-resolved fluorescence protocol. IC 5 o was determined following 10-dose titration (10 gM to 0.508 nM) and four parameter logistic curve fitting using 5 the Merck Assay Data Analyzer.
