Procedure

To a solution of tert-butyl{5-[(2-amino[1,3]thiazolo[5,4-b]pyridin-5-yl)oxy]-2,4-difluorophenyl}carbamate (3.94 g, 10.0 mmol) and N,N-dimethylpyridine-4-amine (1.22 g, 10 mmol) in pyridine (20 mL) was added dropwise acetyl chloride (0.94 g, 12 mmol) under ice-cooling, and the mixture was stirred at room temperature overnight. To the reaction mixture was added water (200 mL), and the mixture was extracted with ethyl acetate (100 mL×2). The ethyl acetate layers were combined, and dried over anhydrous magnesium sulfate. The insoluble material was filtered off, and the filtrate was concentrated under reduced pressure. The obtained residue was triturated with diethyl ether to give the title compound (4.36 g, quantitatively) as a pale-yellow amorphous.
