Procedure
To a solution of 3-bromo-8-[2,6-dichloro-3-[N-methyl-N-[(thiomorpholinoacetyl)glycyl]amino]benzyloxy]-2-methylimidazo[1,2-a]pyridine (200 mg) in methylene chloride (2 ml) was added m-chloroperbenzoic acid (80% purity, 76 mg) under ice-bath cooling, and the mixture was stirred for 1 hour at the same temperature. The reaction mixture was washed with water twice and brine, dried over magnesium sulfate, and concentrated in vacuo. The residue was purified by preparative thin layer chromatography (methylene chloride:methanol=5:1, V/V) to give 3-bromo-8-[2,6-dichloro-3-[N-methyl-N-[[(1-oxothiomorpholino)acetyl]glycyl]amino]benzyloxy]-2-methylimidazo[1,2-a]-pyridine (96 mg) as an amorphous.
