Solid-solid transformation of 5-methyl-2-[(4-methyl-2-nitrophenyl)amino]-3-thiophenecarbonitrile from the dark-red to the red form was investigated. By controlled crystallization, the dark-red form was prepared and the crystals were sieved into fractions: coarse (>250 mm), medium (125-177 mm), and f

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[~
