[4-(Morpholin-4-ylmethyl)phenyl]methanamine → Ethyl 5-(4-chlorophenyl)-2-[4-(morpholinomethyl)phenyl]imidazole-4-carboxylate

Participants

Reaction Steps

4-(Morpholinomethyl)phenylmethylamine (8 g) and ethyl 3-(4-chlorophenyl) -2-hydroxyimino-3-oxopropionate (8.26 g) were dissolved in pyridine (120 ml) and the mixture was refluxed under heating for 12 hr. The solvent was evaporated under reduced pressure and the obtained residue was subjected to silica gel column chromatography to give the objective ethyl 5-(4-chlorophenyl)-2-[4-(morpholinomethyl)phenyl]imidazole-4-carboxylate (8.46 g), melting point 183-185° C.
