## Abstract 2‐Amino‐6‐(3‐methyl‐5‐oxo‐1‐phenyl‐2‐pyrazolin‐4‐yl)‐4‐phenylpyridine‐3‐carbonitrile (1) obtained by the reaction of 4‐(1‐iminoethyl)‐3‐methyl‐1‐phenyl‐2‐pyrazolin‐5‐one with benzylidenemalononitrile, was reacted with triethyl orthoformate followed by hydrazine hydrate, acetic anhydride
A simple four-stage conversion of 2-1nethyl-4(5>nitroimidazole to 2-methyl-4(5)-nitr0['~N""]imidazole is reported. The method consists in N-nitration of the initial compound to ?-methyl-1,4-dinitroimidazole, treating the latter with ["Nlglycine and N-dealkylation of the obtained (~-rnethyl-4-nitro[~
