실험 절차

To a solution of 8-(2,6-dichloro-3-nitrobenzyloxy)-2-methylimidazo[1,2-a]pyridine (85 mg) in a mixture of ethanol (1 ml) and 1,4-dioxane (1 ml) was added in one portion N-bromosuccinimide (43 mg) at ambient temperature. After stirring for one hour at the same temperature, the mixture was filtered to give 3-bromo-8-(2,6-dichloro-3-nitrobenzyloxy)-2-methylimidazo[1,2-a]pyridine (85 mg) as a yellow solid.
