Procedure

To DMF (3 ml) solution of acetanilide (0.14 g) was added sodium hydride (60% in oil: 0.043 g) under ice-cooling, and DMF (2 ml) solution of phenyl N-phenyl-3-(phenylsulfonyl)acrylimidate (0.30 g) was added dropwise. It was stirred for two hours under ice-cooling and for one hour at room temperature. Ethyl acetate (100 ml) was added to the reaction mixture and was successively washed with water and aqueous saturated sodium chloride solution. The organic layer was dried over anhydrous magnesium sulfate, concentrated under reduced pressure. The residue was isolated and purified by silica gel column chromatography (hexane:ethyl acetate=3:1) to obtain phenyl N-phenyl-3-(N′-acetyl-N′-phenylamino)acrylimidate (0.050 g) as yellow crystal.
