Participants

Reaction Steps

A mixture of 1.0 g. of 3-chloro-6-(p-chlorophenyl)-4-methylpyridazine, 0.62 g. of acetic acid hydrazide and 10 ml. of n-butanol is refluxed for 48 hours. The solvent is removed and the residue dissolved in dichloromethane and filtered through magnesol. The solid from the filtrate is recrystallized from dichloromethane-hexane to give 0.6 g. of solid, m.p. 209°-212° C. Recrystallization from dichloromethane-hexane gives the product of the example as light pink colored crystals, m.p. 215°-217° C.
