Procedure

A solution of 0.18 g ethyl 5,6,7,8-tetrahydroimidazo[1,2-a]pyridine-7-carboxylate in 10 ml of 3N-HCl was heated overnight under reflux, the reaction mixture was concentrated to dryness under reduced pressure, and the residue was dried, thus giving 0.18 g of 5,6,7,8-tetrahydroimidazo[1,2-a]pyridine-7-carboxylic acid·hydrochloride.
