Reaction Steps

To a mixture of 8-(3-amino-2,6-dichlorobenzyloxy)-3-bromo-2-methylimidazo[1,2-a]pyridine dihydrochloride (100 mg) and acetone (116 mg) in 3M HCl solution in ethanol (2 ml) was added sodium cyanoborohydride (25 mg) in one portion. The mixture was stirred for 2 hours at ambient temperature and then concentrated in vacuo. The residue was partitioned between ethyl acetate and aqueous sodium bicarbonate solution. The organic layer was dried and concentrated in vacuo to give an oil, which was purified by preparative thin-layer chromatography on silica gel (ethyl acetate:n-hexane=1:2, V/V), to give 3-bromo-8-(2,6-dichloro-3-isopropylaminobenzyloxy)-2-methylimidazo[1,2-a]pyridine as a white solid (50 mg).
