A mixture of 4-fluorophenyl acetone (50 grams) and 162.5 ml of N,N-dimethylformamide dimethyl acetal in 75 ml of acetonitrile is stirred for 12 hours and then the reaction mixture is concentrated on a rotary evaporator. The residual solid is suspended in 100 ml of hexane and filtered to give 59.6 grams of 1-(4-fluorophenyl)-2-(dimethylamino)ethenyl-2-propanone.
