Five grams of 4-(4-aminophenyl)-1-H-imidazole were added to a solution of 4.6 gm of ethyl N-phenyl-formimidate [Org. Synth., 35, 65 (1965)] in 25 ml of acetone. After stirring for four hours at room temperature, the solid that separated was filtered and dried under vacuum. The product was treated with acetone and acidified with glacial acetic acid. N-Phenyl-N'-[4-(imidazol-4-yl]-formamidine crystallized as acetate salt which was filtered to give 4.6 gm of the desired product.
