Reaction of m-nitrobenzylideneacetylacetone with phenyl- and methylhydrazine in aqueous acetonitrile, methanol, and glacial acetic acid afforded 4-(α-hydroxy-, methoxy-, and acetoxy-m-nitrobenzyl)-3,5-dimethyl-1-phenylpyrazoles (Va-VIIa) and the corresponding 1-methyl derivatives (Vb-VIIb), presumably via the pseudo-bases (III), in excellent yields.
