Tetrahydrofuran → 8-[(2-Fluorobenzyl)oxy]-2-methylimidazo[1,2-a]pyridine-3-carboxylic acid

Participants

Reaction Steps

To 2.16 g of ethyl 8-[(2-fluorobenzyl)oxy]-2-methylimidazo[1,2-a]pyridine-3-carboxylate were added 20 ml of THF, 40 ml of ethanol, and 20 ml of a 1 M aqueous sodium hydroxide solution, followed by stirring for 4 days. The solvent was evaporated under reduced pressure, and water and 1 M hydrochloric acid were added thereto. The insoluble material was collected by filtration and dried to obtain 1.99 g of 8-[(2-fluorobenzyl)oxy]-2-methylimidazo[1,2-a]pyridine-3-carboxylic acid.
