A mixture of 11.4 g. of 6-(m-nitrophenyl)-3-chloropyridazine, 8.25 g. of methyl carbazate and 150 ml. of n-butanol is refluxed for 3 hours. The solvent is removed and the oily redisue stirred with cold water. The solid is filtered to give 11.5 g. of crystals which are recrystallized from methanol-petroleum ether to give off-white crystals, m.p. 198°-199° C.
