To a solution of N-{3-[(2-amino[1,3]thiazolo[5,4-b]pyridin-5-yl)oxy]-4-cyanophenyl}-3-(1-cyano-1-methylethyl)benzamide (150 mg, 0.330 mmol) produced in Example C43(vi) in N,N-dimethylformamide (3.0 mL) was added chloroacetyl chloride (42 μL, 0.528 mmol), and the mixture was stirred at room temperature for 4 hr. Chloroacetyl chloride (21 μL, 0.264 mmol) was further added, and the mixture was stirred at room temperature for 12 hr. The reaction mixture was diluted with ethyl acetate (100 mL), washed with 5% aqueous sodium hydrogen carbonate solution (100 mL) and saturated brine (100 mL), and dried over anhydrous sodium sulfate. The insoluble material was filtered off, and the filtrate was concentrated under reduced pressure to give N-[3-({2-[(chloroacetyl)amino][1,3]thiazolo[5,4-b]pyridin-5-yl}oxy)-4-cyanophenyl]-3-(1-cyano-1-methylethyl)benzamide as a colorless solid.
