Abstract
Abstract 2-methyl-4-nitro-1-phenylimidazole undergoes a nucleophilic substitution of hydrogen in reaction with 4-amino-1,2,4-triazole in the presence of MeONa in DMSO yielding 5-amino-2-methyl-4-nitro-1-phenylimidazole, whereas in reaction with hydroxylamine in the presence of KOH in methanol undergoes a transformation to 4-acetylamino-1-oxy-2-phenyl-2H-1,2,3-triazole. A structure of the latter compound was confirmed by X-ray analysis.
