Chloroacetyl chloride → N-[3-({2-[(chloroacetyl)amino][1,3]thiazolo[5,4-b]pyridin-5-yl}oxy)-4-ethylphenyl]-3-(1-cyano-1-methylethyl)benzamide

Participants

Reaction Steps

To a solution of N-{3-[(2-amino[1,3]thiazolo[5,4-b]pyridin-5-yl)oxy]-4-ethylphenyl}-3-(1-cyano-1-methylethyl)benzamide (150 mg, 0.327 mmol) in N,N-dimethylformamide (4.0 mL) was added chloroacetyl chloride (34 μL, 0.425 mmol), and the mixture was stirred at room temperature for 2 hr. The reaction mixture was diluted with ethyl acetate (100 mL), washed with 5% aqueous sodium hydrogen carbonate solution (100 mL) and saturated brine (50 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-ethylphenyl]-3-(1-cyano-1-methylethyl)benzamide as a colorless solid.
