反应详情

A solution of 2-benzyl-4-methoxy-N-methylbenzamide (125 mg) in 5 mL THF was cooled to −78 C. n-BuLi (0.400 mL, 2.5 M in hexanes) was added, and the reaction was stirred at −78 C for 20 min. A solution of ethyl formate (0.160 mL) in 1 mL THF was added via cannula. The reaction was quenched at −78 C by addition of saturated aqueous ammonium acetate. The mixture was extracted with EtOAc and concentrated to give 4-methoxy-N-methyl-2-(2-oxo-1-phenylethyl)benzamide, which was used without further purification.
