Participants

Reaction Steps

6.0 (28.9 millimoles) of 1,4-dihydro-4-imino-1-phenylpyridazine hydrochloride in 50 ml of benzoyl chloride were kept at 120° C. for 10 hours, while stirring. The mixture was cooled and then filtered under suction, and the residue was washed with acetone and recrystallized from isopropanol. 3.3 g (37% of theory) of 4-benzoylimino-1,4-dihydro-1-phenylpyridazine hydrochloride were isolated as pale beige crystals of melting point 225°-226° C. (decomposition).
