Procedure

To a solution of N-{5-[(2-amino[1,3]thiazolo[5,4-b]pyridin-5-yl)oxy]-4-chloro-2-fluorophenyl}-3-(1-cyano-1-methylethyl)benzamide (150 mg, 0.311 mmol) produced in Example C52(v) in N,N-dimethylacetamide (2.0 mL) was added chloroacetyl chloride (50 μL, 0.622 mmol), and the mixture was stirred at room temperature for 2 hr. The reaction mixture was diluted with ethyl acetate (20 mL), washed with 5% aqueous sodium hydrogen carbonate solution (10 mL) and saturated brine (10 mL), and dried over anhydrous sodium sulfate. The insoluble material was filtered off, and the filtrate was concentrated under reduced pressure to give N-[4-chloro-5-({2-[(chloroacetyl)amino][1,3]thiazolo[5,4-b]pyridin-5-yl}oxy)-2-fluorophenyl]-3-(1-cyano-1-methylethyl)benzamide as an oily residue.
