Procedure
To a solution of 1.483 g (3.61 mmol) of 5-(2-pyridyl)methylene-3-[4-(imidazo[1,2-a]pyridin-5-ylthio)butyl]thiazolidine-2,4-dione in 30 ml of methanol, 0.42 ml of concentrated hydrochloric acid was added. After the solvent was distilled off, the residue was crystallized from dichloromethane-diethyl ether to yield 1.61 g (99.8%, white crystal) of the desired product.
