Reaction Steps

To a solution of 2-methyl-5,6-dinitro-benzimidazole in 5% NaOH was added methanol and dimethyl sulfate. The reaction mixture was heated for 30 min at 90-95° C. and then cooled to room temperature. The precipitate which formed was filtered, washed with 10% NaOH and then water, and dried overnight at 40° C. to yield 1,2-dimethyl-5,6-dinitrobenzimidazole.
