To a solution of 3-cyano-N-methoxy-N-methyl-5-(trifluoromethyl)benzamide (196 mg, 0.76 mmol) in anhydrous tetrahydrofuran (2 mL) stirred on an ice bath was added methylmagnesium bromide (0.96 M solution in ether, 0.95 mL, 0.91 mmol), and the mixture was stirred at room temperature for 15 minutes. The reaction mixture was added with 1 M hydrochloric acid, and extracted with ethyl acetate, and then the organic layer was washed with saturated brine, dried over anhydrous sodium sulfate, and then concentrated under reduced pressure to obtain 3-acetyl-5-(trifluoromethyl)benzonitrile (162 mg, 100%) as a pale yellow oil.
