Procedure

A mixture of 5.49 g. of 5-methyl-6-(m-nitrophenyl)-3-chloropyridazine and 8.71 g. of t-butylcarbazate in 100 ml. of butanol is heated at reflux for 3 hours and then allowed to cool to room temperature overnight. The butanol is removed on a rotating evaporator leaving a heavy liquid residue. The final product is obtained after crystallization from a minimum amount of methanol on standing, washing with methanol, water and drying, m.p. 160°-162° C.
