Reaction Steps

A mixture of 5-methyl-2-phenyl-4imidazolecarboxaldehyde (10.25 g), ethyl carbazate (5.72 g) and ethanol (30 ml) containing 1 drop of acetic acid is heated at the boil for 30 minutes. The mixture is then concentrated under an air stream on a steam bath. Next, carbon tetrachloride (50 ml) is added and the mixture cooled at 0° C overnight. The solid is collected giving the title product, m.p. 209°-211° C.
