실험 절차

An exemplary starting compound, 5-amino-1-methyl-3-(1-methyl-5-nitro-2-imidazolyl)pyrazole-4-carbonitrile, is readily synthesized starting from commercially-available 2-methyl-5-nitroimidazole. The 2-methyl-5-nitroimidazole is allowed to react with a suitable alkylating agent, such as dimethyl sulfate, in a suitable solvent, for example benzene, to yield the compound identified as 1,2-dimethyl-5-nitroimidazole. This latter compound is in turn allowed to react with benzaldehyde in the presence of a base, for example sodium ethoxide in absolute ethanol, to yield 1-methyl-5-nitro-2-styrylimidazole.
