Procedure

To a mixture of ethyl 2-(6-cyclohex-1-en-1-yl-2-methylimidazo[1,2-a]pyridin-3-yl)-4-phenyl-1,3-thiazole-5-carboxylate (200 mg, 0.45 mmol) obtained above in acetic acid (18 mL) and MeOH (18 mL), was added 10% palladium-carbon (100 mg), and the mixture was stirred at rt for 15 h under a hydrogen atmosphere (1 atm). Insoluble materials were removed by filtration, and the filtrate was concentrated under reduced pressure. To the residue was added saturated aqueous solution of sodium bicarbonate (10 mL) and water (10 mL), and the resulting precipitate was collected by filtration, which was washed with diethyl ether to give the title compound (154 mg, 69%) as a black solid.
