Procedure

To a solution of 1.26 g (3.78 mmol) of 5-butylidene-3-(imidazo[1,2-a]pyridin-5-ylthio)methylthiazolidine-2,4-dione in 30 ml of methanol, 0.5 ml of concentrated hydrochloric acid was added. After the solvent was distilled off, the residue was washed with diethyl ether to yield 1.33 g (100%, light yellow solid) of the desired product.
