Procedure

To a solution of N-{3-[(2-amino[1,3]thiazolo[5,4-d]pyrimidin-5-yl)amino]-4-methylphenyl}-3-(1-cyano-1-methylethyl)benzamide (137 mg, 309 μmol) in pyridine (3 mL) was added cyclopropanecarbonyl chloride (68 μL, 742 μmol), and the mixture was stirred at room temperature for 2 hr. To the reaction mixture was added saturated aqueous sodium hydrogen carbonate solution (20 mL), and the mixture was extracted with ethyl acetate/tetrahydrofuran mixture (9:1, 20 mL, 5 mL). The combined organic layer was washed with saturated brine (5 mL), and dried over anhydrous sodium sulfate. The insoluble material was filtered off, and the filtrate was concentrated under reduced pressure. The obtained residue was recrystallized from methanol and ethyl acetate to give the title compound (56 mg, 35%) as pale-red crystals.
