実験手順
To a suspension of 3-bromo-8-(2,6-dichloro-3-nitrobenzyloxy)-2-methylimidazo[1,2-a]pyridine (200 mg) in ethanol (2 ml) was added hydrogen chloride in ethanol (3.5 Mol solution, 1 ml). The solution was concentrated to half volume under reduced pressure. The separated precipitates were collected by filtration and washed with ethanol to give 3-bromo-8-(2,6-dichloro-3-nitrobenzyloxy)-2-methylimidazo[1,2-a]pyridine hydrochloride (175 mg) as an off-white solid.
