Potassium Carbonate → [3-(Dimethoxymethyl)-4-nitrophenyl]phenylmethanone

Participants

Reaction Steps

A mixture of 26.7 parts of intermediate 9, namely 3-(dimethoxymethyl)-4-nitro-α-phenylbenzeneacetonitrile, 12.3 parts of potassium carbonate and 360 parts of N,N-dimethylacetamide was stirred at room temperature while bubbling air through it. The reaction mixture was poured into water and the whole was extracted with dichloromethane. The extract was dried, filtered and evaporated and the residue was purified by column chromatography (silica gel; CHCl3 /hexane 80:20). The eluent of the desired fraction was evaporated, yielding 18.1 parts (67.3%) of [3-(dimethoxymethyl)-4-nitrophenyl]phenylmethanone (interm. 10).
