Reaction Steps

A suspension of 500 mg of ethyl 8-hydroxy-2-methylimidazo[1,2-a]pyridine-3-carboxylate, 0.35 ml of 2,3-difluorobenzylbromide, and 650 mg of potassium carbonate in 8.6 ml of N,N-dimethylformamide (DMF) was stirred at 60° C. for 1 hour. The reaction mixture was left to be cooled to room temperature and water was then added thereto. The resulting solid was collected by filtration and washed with water. The solid was washed with diisopropyl ether to obtain 650 mg of ethyl 8-[(2,3-difluorobenzyl)oxy]-2-methylimidazo[1,2-a]pyridine-3-carboxylate.
