^sD ci FIELD OF THE INVENTION The present invention is in the field of medicinal chemistry and relates to compounds that are protein kinase inhibitors, compositions containing such compounds and methods of usd. More particularly, this invention relates to compounds that are inhibitors of GSK-3 and Aurora-2 protein kinases. The invention also relates to methods of treating diseases associated with these protein kinases, such as diabetes, cancer and Alzheimer's disease.
BACKGROUND OF THE INVENTION The search for new therapeutic agents has been greatly aided in recent years by better understanding of the structure of enzymes and other biomoleculies associated with target diseases. One important class of enzymes that has been the subject of extensive study is the protein kinases.
Protein kinases mediate intracellular signal transduction. They do this by effecting a phosphoryl transfer from a nucleoside triphosphate to a protein acceptor that is involved in a signaling pathway. There -la- N are a number of kinases and pathways through which o extracellular and other stimuli cause a variety of ci cellular responses to occur inside the cell. Examples of Ssuch stimuli include environmental and chemical stress signals osmotic shock, heat shock, ultraviolet radiation, bacterial endotoxin, H202), cytokines (e.g.
tinterleukin-i (IL-1) and tumor necrosis factor a (TNF- CI and growth factors granulocyte'macrophage- 0 colony-stimulating factor (GM-CSF), and fibroblast growth ci S 10 factor (FGF). An extracellular stimulus may effect one 0 or more cellular responses related to cell growth, migration, differentiation, secretion of hormones, activation of transcription factors, muscle contraction, glucose metabolism,>control of protein synthesis and regulation of cell cycle.
Many diseases are associated with abnormal cellular responses triggered by protein kinase-mediated events. These diseases include autoimmune diseases, inflammatory diseases, neurological and neurodegenerative diseases, cancer, cardiovascular diseases, allergies and asthma, Alzheimer's disease or hormone-related diseases.
Accordingly, there has been a substantial effort in medicinal chemistry to find protein kinase inhibitors that are effective as therapeutic agents.
Aurora-2 is a serine/threonine protein kinase that has been implicated in human cancer, such as colon, breast and other solid tumors. This kinase is believed to be involved in protein phosphorylation events that regulate the cell cycle. Specifically, Aurora-2 may play a role in controlling the accurate segregation of chromosomes during mitosis. Misregulation of the cell cycle can lead to cellular proliferation and other abnormalities. In human colon cancer tissue, the aurora- CD 2 protein has been found to be overexpressed. See C- -Bischoff et al., EMBO 1998, 17, 3052-3065; Schumacher M et al., J. Cell Biol., 1998', 143, 1635-1646; Kimura et al., J. Biol. Chem., 1997, 272, 13766-13771.
Ci 5 Glycogen synthase kinase-3 (GSK-3) is a serine/threonine protein kinase comprised of a and J QD isoforms that are each encoded by distinct genes [Coghlan c-i et al., Chemistry Biology, 7, 793-803 (2000); Kim and C Kimmel, Curr. Opinion Genetics Dev., 10, 508-514 (2000)].
o 10 GSK-3 has been implicated in various diseases including C-q diabetes, Alzheimer's disease, CNS disorders such as manic depressive disorder and neurodegenerative diseases, and cardiomyocete hypertrophy [WO 99/65897; WO 00/38675; and Haq et al., J. Cell Biol. (2000) 151, 117]. These diseases may be caused by, or result in, the abnormal operation of certain cell signaling pathways in which GSK-3 ,plays a role. GSK-3 has been found to phosphorylate and modulate the activity of a number of regulatory proteins. These proteins include glycogen synthase which is the rate limiting enzyme necessary for glycogen synthesis, the microtubule associated protein Tau, the gene transcription factor p-catenin, the translation initiation factor elF2B, as well as ATP citrate lyase, axin, .heat shock factor-1, c-Jun, c-Myc, c-Myb, CREB, and CEPBa. These diverse protein targets implicate GSK-3 in many aspects of cellular metabolism, proliferation, differentiation and development.
In a GSK-3 mediated pathway that is relevant for the treatment of type II diabetes, insulin-induced signaling leads to cellular glucose uptake and glycogen synthesis. Along this pathway, GSK-3 is a negative regulator of the insulin-induced signal. Normally, the presence of insulin causes inhibition of GSK-3 mediated D phosphorylation and deactivation of glycogen synthase.
C The inhibition of GSK-3 leads to increased glycogen synthesis and glucose uptake [Klein et al., PNAS, 93, 8455-9 (1996); Cross et al., Biochem. 303, 21-26 ^c 5 (1994); Cohen, Biochem. Soc. Trans., 21, 555-567 (1993); Massillon et al., Biochem J. 299, 123-128 (1994)].
However, in a diabetic patient where the insulin response C-I is impaired, glycogen synthesis and glucose uptake fail o to.increase despite the presence of relatively high blood levels of insulin. This leads to abnormally high blood ^c levels of glucose with acute and long term effects that may ultimately result in cardiovascular disease, renal failure and blindness. In such patients, the normal insulin-induced inhibition of GSK-3 fails to occur. It has also been reported that in patients with type II diabetes, GSK-3 is overexpressed [WO 00/38675].
Therapeutic inhibitors of GSK-3 are therefore potentially useful for treating diabetic patients suffering from an impaired response to insulin.
GSK-3 activity has also been associated.with Alzheimer's disease. This disease is characterized by the well-known amyloid peptide and the formation of intracellular neurofibrillary tangles. The neurofibrillary tangles .contain hyperphosphorylated Tau .protein where Tau is phosphorylated on abnormal sites.
GSK-3 has been shown to phosphorylate these abnormal sites in cell and animal models. Furthermore, inhibition of GSK-3 has been shown to prevent byperphosphorylation of Tau in cells [Lovestone et al., Current Biology 4, 1077-86 (1994); Brownlees et al., Neuroreport 8, 3251-55 Therefore, it is believed that GSK-3 activity may promote generation of the neurofibrillary tangles and the progression of Alzheimer's disease..
SAnother substrate of GSK-3 is P-catenin which "C is degradated after phosphorylation by GSK-3. Reduced levels of P-catenin have been reported in schizophrenic patients and have also been associated with other diseases related to increase in neuronal cell death [Zhong et al., Nature, 395, 698-702 (1998); Takashima et ND al., PNAS, 90, 7789-93 (1993); Pei et al., J.
Neuropathol. Exp, 56, 70-78 (1997)].
As a result of the biological importance of S 10 GSK-3, there is current interest in therapeutically effective GSK-3 inhbitors. Small molecules that inhibit GSK-3 have recently been reported [WO 99/65897 (Chiron) and WO 00/38675 (SmithKline Beecham)]. For many of the aforementioned diseases associated with abnormal GSK-3 activity, other protein kinases have also been targeted for treating the same diseases. However, the various protein kinases often act through different biological pathways. For example, certain quinazoline derivatives have been reported -recently as inhibitors of p38 kinase (WO 00/12497 to Scios). The compounds are reported to be useful for treating conditions characterized.by enhanced p38-a activity and/or enhanced TGF-P activity. While p38 activity has been implicated in a wide variety of diseases, including diabetes, p38 kinase is not reported to be a constituent of an insulin signaling pathway that regulates glycogen synthesis or glucose uptake.
Therefore, unlike GSK-3, p38 inhibition would not be expected to enhance glycogen synthesis and/or glucose uptake.
There is a continued need to find new therapeutic agents to treat human diseases. The protein kinases aurora-2 and GSK-3 are especially attractive D targets for the discovery of new therapeutics due to C their important role in cancer, diabetes, Alzheimer's Sdisease and other diseases.

IQD The compounds of this invention may be prepared o as illustrated by the Synthetic Methods below, by the rC Synthetic Examples described herein and by general Smethods known to those skilled in the art.
General Synthetic Methods The general synthetic methods below provide a series of general .reaction routes that were used to prepare compounds of_this invention. Methods A-F below 10 are particularly useful for preparing formula II 0 compounds. In most cases, Ring C is drawn as a phenyl Cs ring bearing an ortho R 1 substituent. However, it will be Sapparent to one skilled in the art that compounds having other Ring C groups may be obtained in a similar manner.
Methods analogous to methods A-F are also useful for 'preparing other compounds of this invention. Methods F-I below are particulary useful for preparing compounds of formula III or IV.

1 R N I RY' N 2 .l Method A is a general route for the preparation of compounds wherein ring C is an aryl or heteroaryl ring. Preparation of the starting dichloropyrimidine 1 may be achieved in a manner similar to that described in Chem. Pharm.'Bull., 30, 9, 1982, 3121-3124. The chlorine in position 4 of intermediate 1 may be replaced by an aminopyrazole or aminoindazole to provide intermediate 2 228 \D in a manner similar to that described in J. Med. Chem., 0 38, 3547-3557 (1995). Ring C is then introduced using a (c boronic ester under palladium catalysis (see Tetrahedron, S48, 37, 1992, 8117-8126). This method is illustrated by the following procedure.
A suspension of lH-quinazoline-2,4-dione (10.0 g, 61.7 mmol) in POC13 (60 mL, 644 mmol) and N,Ndimethylaniline (8mL, 63.1 mmol) is heated under reflux S* for 2 h. Excess POCI 3 is evaporated under vacuum, the '10 residue is poured into ice, and the precipitate is o collected by filtration. The crude solid 2,4- ND dichloroquinazoline product may be used without further Spurification.
To a solution of 2,4-dichloro-quinazoline (3.3 g, 16.6 mmol) in anhydrous ethanol (150 mL) is added methyl-lH-pyrazol-3-yl amine (3.2 g, 32.9 mmol). The mixture is stirred at room temperature for 4 h, and the resulting precipitate is collected by filtration, washed with ethanol, and dried under vacuum to afford (2-chloroquinazolin-4-yl) (5-methyl-lH-pyrazol-3-yl) -amine.
To a solution of (2-chloro-quinazolin-4-yl)-(5methyl-1H-pyrazol-3-ylY-amine (50 mg, 0.19 mmol) in DMF mL) is added the desired arylboronic acid (0.38 mmol), 2M Na2CO3 (0.96 mmol), and tri-t-butylphosphine (0.19 mmol). Under-nitrogen, PdCl 2 (dppf) (0.011 mmol) is added in one. portion. The reaction mixture is then.
heated at 80OC for 5 to 10 hours, cooled to room temperature, and poured into water (2 mL). The resulting precipitate :is collected by filtration, washed with water, and purified by HPLC.

S A 6 (iii) 7 Methods B through F describe routes where the pyrazole ring system is introduced after Ring C and the pyrimidine ring portion are first constructed. A versatile intermediate is the 4-chloropyrimidine 4, which is readily obtained from pyrimidinone 3- as shown in Method This reaction sequence is generally applicable for a variety of Ring C groups including aliphatic, aryl, beteroaryl, or heterocyclyl. See J.
Med. Chem., 38, 3547-3557 (1995).

0 BIOLOGICAL TESTING o ^c The activity of the compounds as protein kinase inhibitors may be assayed in vitro, in vivo or in a cell line. In vitro assays include assays that determine inhibition of either the phosphorylation activity or C ATPase activity of the activated protein kinase.
Alternate in vitro assays quantitate the ability of the Sinhibitor to bind to the protein kinase. Inhibitor binding may be measured by radiolabelling the inhibitor o prior to binding, isolating the inhibitor/protein kinase \D complex and determining the amount of radiolabel bound.
o Alternatively; inhibitor binding, may be determined by C( running a competition experiment where new inhibitors are incubated with the protein kinase bound to known radioligands.
