Phenyl 3-(N′-methyl-N′-phenylamino)-N-phenylacrylimidate phenyl 3-(phenoxy)-N-phenylacrylimidate (0.39 g) was dissolved to acetonitrile (5 ml), and N-methylaniline (0.20 g) and catalytic amount of N,N-dimethylaminopyridine were added at room temperature. It was stirred for two hours at the same temperature and for eight hours under heat refluxing. It was concentrated under reduced pressure. The residue was subjected to silica gel column chromatography (hexane:ethyl acetate=10:1) to obtain phenyl 3-(N′-methyl-N′-phenylamino)-N-phenylacrylimidate (0.17 g) as light brown crystal.
