실험 절차

5 drops of 3M sodium hydroxide solution were added to a mixture of 160 mg (0.52 mmol) of N-[[N-(2-acetylphenyl)-N-methylcarbamoyl]methyl]pivalamide and 100 mg (0.57 mmol) of 3,4-dichlorobenzaldehyde in 3 ml of methanol. After 1 hr at room temperature the solvent was removed by evaporation and the residue chromatographed on silica gel using ethyl acetate/petrol (55:45) for the elution. There was obtained 65 mg of (E)-N-[[N-[2-[3-(3,4-dichlorophenyl)acryloyl]phenyl]-N-methylcarbamoyl]methyl]pivalamide as a yellow gum. MS: m/e 463 [M+H]+.
