[0120] To pale yellow stirring mixture of N4-(2,2-dimethyl-3-oxo-4H-5-pyrido[1,4]oxazin-6-yl)-5-fluoro-N2-(3,4,5-trimethoxyphenyl)-2,4-pyrimidinediamine (2.5 g, 5.31 mmol) and triphosgene (1.67 g, 5.62 mmol) in dicholoroethane (20 mL) at 0 0C, NEt3 (1.08 g, 1.5 mL, 10.76 mmol) in dichloroethane (10 mL) was added dropwise under nitrogen atmosphere for 10 min. The orange reaction mixture was allowed to stir for 15 min at 0 0C followed by refluxing at 90 0C overnight. The heterogeneous tan orange reaction mixture was cooled to room temperature. The reaction mixture was diluted with EtOAc (75 mL). Precipitated white solid formed was filtered. The white solid was collected, treated with water, filtered and dried to provide N2-chlorocarbonyl-N4-(2,2-dimethyl-3-oxo-4H-5-pyrido[1,4]oxazin-6-yl)-5-fluoro-N2-(3,4,5-trimethoxyphenyl)-2,4-pyrimidine...

Description

CROSS-REFERENCE TO RELATED APPLICATION [0001] This application is a continuation of U.S. patent application Ser. No. 11 / 295,752 filed Dec. 6, 2005, from which priority is claimed and which application is incorporated herein by reference in its entirety.FIELD OF INVENTION [0002] The invention relates to compounds containing the pyrimidine-2,4-diamine moiety, particularly diaryl pyrimidine-2,4-diamines, compositions comprising the compounds, and methods of using the compounds and compositions for the inhibition of kinases. The compounds and compositions are useful for treating or modulating disease in which kinases may be involved, symptoms of such disease, or the effect of other physiological events mediated by kinases. BACKGROUND OF THE INVENTION [0003] The protein kinases constitute a large family of structurally related enzymes that are responsible for the control of a wide variety of signal transduction processes within the cell. (Hardie and Hanks (1995) The Protein Kinase Facts ...
