실험 절차

1-[5-(Trifluoromethyl)phenyl]ethanone (0.20 mL, 0.0013 mol) and 1,1-dimethoxy-N,N-dimethylmethanamine (0.17 mL, 0.0013 mol) were combined in a sealed tube and heated in a microwave to 120° C. for 15 minutes, the reaction was allowed to cool and was concentrated to remove the residual DMF acetal, to give (2E)-3-(dimethylamino)-1-[3-(trifluoromethyl)phenyl]prop-2-en-1-one, 0.32 gm, as a red oil, LC/MS (M+H)+: 244.
