Procedure

N-[2-(2-Methyl-6,7-dihydro-8H-indeno[5,4-d][1,3]thiazol-8-ylidene)ethyl]acetamide (61.0 mg, 0.224 mmol) was dissolved in methanol (3 mL), a 10% palladium-carbon powder (10 mg) was added, and the mixture was stirred at room temperature for 15 hr under a hydrogen atmosphere. The catalyst was filtered off using celite, and the filtrate was concentrated under reduced pressure. The residue was purified by silica gel column chromatography (ethyl acetate/methanol=100/0-95/5) to give the title compound (49.6 mg, yield 81%).
