実験手順

A mixture of 3-acetamidoacetophenone 7 (20 g, 112.9 mmol), dimethylformamide dimethyl acetal (40.3 g, 338.6 mmol) was refluxed under nitrogen for 1 hour. The reaction mixture was cooled, diluted with ethyl acetate (150 mL) and ether (150 mL). The solid was collected by filtration, triturated with a solution of ethyl acetate and hexane (1:1, 200 mL). Compound 8 was obtained as a red-orange solid (23.6 g, 101.6 mmol, 90%). GC/MS, m/z=232 at tR=15.11 min (100%). LC/MS, [M+H]′=233.
