Participants

Reaction Steps

An amount of 1.4 g. of 6-chloro-4-(1-methylhydrazino)-1H-2,3-benzoxazine is dissolved in 70 ml. of ethanol by heating at 50° C, then 1.12 g. of p-nitro-benzaldehyde are added. The solution is stirred, then allowed to stand for 2 hours. The formed crystals are collected by filtering and recrystallized from 500 ml. of benzene. An amount of 1.7 g. (74%) of 6-chloro-4-[1-methyl-2-(4-nitro-benzylidene)-hydrazino]-1H-2,3-benzoxazine are obtained; m.p. 251° C with decomposition.
