Reaction Steps

A mixture of 5.1 g of 2-phenyl-5,6,7,8-tetrahydroimidazo[2',1':2,3]thiazolo[5,4-c]pyridine, 10 g of 10% palladium carbon and 150 ml of mesitylene was refluxed with heating for 19 hours. After the catalyst was filtered off, the solvent was distilled off. To the residue was added n-hexane and crystals were filtered off. The crude crystals were recrystallized from ethyl acetate to give 2.7 g of 2-phenylimidazo[2',1':2,3]thiazolo[5,4-c]pyridine, melting at 183°-185° C.
