실험 절차

A mixture of 14.5 g (0.1 moles) of 3-chloro-6-pyridazinyl-hydrazine, 8.5 g (0.1 moles) of 3-iminobutyronitrile and 150 ml of ethanol is heated to reflux for 9 hours. After cooling the separated crystals are filtered, washed with ethanol and dried. Yield: 15.6 g (74.0%); m.p.: 148°-150° C. The hydrochloride melts at 157°-159° C.
