Procedure

To a solution of 310 mg (0.823 mmol) of 5-(dimethylamino)methylene-3-[4-(imidazo[1,2-a]pyridin-5-ylthio)butyl]thiazolidine-2,4-dione in 10 ml of methanol, concentrated hydrochloric acid was added. After the solvent was distilled off, the residue was washed with diethyl ether to yield 311 mg (84.1%, white powder) of the desired product.
