Participants

Reaction Steps

4-(Dimethylaminomethyl)phenylmethylamine (11.7 g) and ethyl 3-(4-chlorophenyl)-2-hydroxyimino-3-oxopropionate (15.1 g) were dissolved in pyridine (220 ml) and the solution was refluxed under heating for 12 hr. The solvent was concentrated under reduced pressure and the obtained residue was subjected to silica gel column chromatography to give the objective ethyl 5-(4-chlorophenyl)-2-[4-(dimethylaminomethyl)phenyl]imidazole-4-carboxylate (9.0 g), melting point 175-176° C.
