Participants

Reaction Steps

Under an argon gas flow, to a suspension of 32.5 g of 8-[(2,6-difluorobenzyl)oxy]-2-methylimidazo[1,2-a]pyridine-3-carboxylic acid in 807 ml of dichloromethane were added 190 μl of DMF and 17.2 ml of oxalyl chloride under ice-cooling, followed by stirring at room temperature for 80 minutes. The reaction mixture was concentrated under reduced pressure to obtain 38.0 g of 8-[(2,6-difluorobenzyl)oxy]-2-methylimidazo[1,2-a]pyridine-3-carbonyl chloride hydrochloride.
