Reaction Steps

To a solution of 3-bromo-8-[2,6-dichloro-3-[N-(N-mesyloxyacetylglycyl)-N-methylamino]benzyloxy]-2-methylimidazo[1,2-a]pyridine (100 mg) in methanol (2 ml) was added sodium methoxide (317 mg), and the mixture was stirred for 1 hour. Sodium methoxide (200 mg) was added thereto, and the mixture was stirred for 3 hours. To the reaction mixture was added water, and the mixture was extracted with methylene chloride 3 times. The extracts were combined, washed with brine, dried over magnesium sulfate and concentrated in vacuo. The residue was purified by preparative thin-layer chromatography (methylene chloride:methanol=10:1, V/V) to give 3-bromo-8-[2,6-dichloro-3-[N-(methoxyacetylglycyl)-N-methylamino]benzyloxy]-2-methylimidazo[1,2-a]pyridine (60 mg).
