Procedure

To a solution of (4-amino-2-chloro-pyrimidin-5-yl)-[3-(tert-butyl-dimethyl-silanyloxy)-5,6-difluoro-2-methoxy-phenyl]-methanone (860 mg, 2.0 mmol, Example 269) in ethanol (12 mL) was added 1-methanesulfonyl-piperidin-4-ylamine trifluoroacetate salt (613.8 mg, 2.1 mmol, Example 162) and diisopropylethylamine (1.2 mL, 6.889 mmol). The mixture was heated at reflux for 4 hours and then concentrated to dryness. The residue was dissolved in ethyl acetate (20 mL). The solution was washed with brine (1×10 mL) and dried over anhydrous magnesium sulfate. The solids were filtered off and the filtrate was concentrated in vacuo. Purification of the crude residue by flash chromatography (Biotage system, 60 Å silica gel, eluting with 45–60% ethyl acetate in hexanes) yielded [4-amino-2-(1-methanesulfonyl-piperidin-4-ylamino)-pyrimidin-5-yl]-[3-(tert-butyl-dimethyl-silanyloxy)-5,6-difluoro-2-methoxy-phenyl]-methanone as white glass (684 mg, 60%). LR-MS (M+) 572.1.
