Acetyl chloride → N-(3-{[2-(acetylamino)[1,3]thiazolo[5,4-d]pyrimidin-5-yl]amino}-4-methylphenyl)-3-(1-cyano-1-methylethyl)benzamide

Participants

Reaction Steps

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 (161 mg, 363 μmol) produced in Example D25(iii) in pyridine (4 mL) was added acetyl chloride (65 μL, 908 μmol), and the mixture was stirred at room temperature for 1 hr. To the reaction mixture was added saturated aqueous sodium hydrogen carbonate solution (20 mL), and the mixture was extracted with ethyl acetate (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 ethyl acetate to give the title compound (129 mg, 73%) as colorless crystals.
