Reaction Steps

1.612 g (5 mmol) of 3-[4-(imidazo[1,2-c]pyrimidin-5-ylthio)butyl]thiazolidine-2,4-dione and 20 ml of ethanol were placed in a reaction flask, followed by stirring at 60° C. for 20 minutes, to dissolve the starting materials. After this mixture was kept standing to 50° C., an ethanol solution of 0.05 ml (0.5 mmol) of piperidine was added. Next, an ethanol solution of 0.45 ml (5 mmol) of n-butyraldehyde was added, followed by refluxing for 100 minutes. After the reaction mixture was cooled, the solvent was distilled off, followed by extraction with dichloromethane and water. After the organic layer was dried with sodium sulfate, the solvent was distilled off. The residue was eluted by column chromatography (eluent, hexane/ethyl acetate=1/4) to yield 1.052 g (55.9%, white crystal) of the desired product.
