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[~
