2-(3,4-Dichlorophenyl)-N-methoxy-N-methylacetamide → 2-(3,4-Dichlorophenyl)-1-phenylethanone

Participants

Reaction Steps

Under N2, to a mixture of 2-(3,4-dichlorophenyl)-N-methoxy-N-methylacetamide (440 mg, 1.8 mmol) in anhydrous THF was added phenylmagnesium bromide (4.4 mL, 4.4 mmol) at −78° C., and the mixture was stirred for 3 hours. When TLC indicated that the starting material was consumed, the reaction mixture was diluted with EtOAc, washed with water and brine, concentrated, and purified by column chromatography (PE:EtOAc=20:1) to give Intermediate 6 (400 mg, yield 85%).
