Participants

Reaction Steps

A mixture of 3-bromo-8-[3-(N-acetoxyacetyl-N-methylamino)-2,6-dichlorobenzyloxy]-2-methylimidazo[1,2-a]pyridine (1.42 g), potassium carbonate (761 mg), methanol (7 ml) and tetrahydrofuran (7 ml) was stirred at ambient temperature for 1 hour. The mixture was partitioned between dichloromethane and water. The aqueous layer was extracted with dichloromethane twice. The combined organic layers were washed with brine, dried over magnesium sulfate and evaporated in vacuo. The residue was crystallized from ethanol to give 3-bromo-8-[2,6-dichloro-3-(N-glycoloyl-N-methylamino)benzyloxy]-2-methylimidazo[1,2-a]pyridine (1.16 g) as crystals.
