Nitric Acid → 2-Methyl-5-nitroimidazole

Participants

Reaction Steps

A method for the safe nitration of 2-methylimidazole with high output comprising nitrating the 2-methylimidazole with nitric acid and sulfuric acid as nitrating agents to produce 2-methyl-5-nitroimidazole, and controlling the reaction by adding as an inhibitor the reaction product itself or an excess of the concentrated nitric acid. The reaction can be carried out in stages with a reduced temperature in the first stage and an increased temperature in a subsequent stage.
