实验过程

To a solution of 2-[3,5-bis(difluoromethyl)-1H-pyrazol-1-yl]-1-(4-{4-[5-(2-nitrophenyl)-4,5-dihydro-1,2-oxazol-3-yl]-1,3-thiazol-2-yl}piperidin-1-yl)ethanone (80 mg) in methanol (10 ml) is added, at room temperature, Pd/C (20 mg, 10%). The reaction mixture is stirred under a hydrogen atmosphere at room temperature for 3 hours, then volatile constituents are removed under reduced pressure. Purification by column chromatography gives 1-(4-{4-[5-(2-aminophenyl)-4,5-dihydro-1,2-oxazol-3-yl]-1,3-thiazol-2-yl}piperidin-1-yl)-2-[3,5-bis(difluoromethyl)-1H-pyrazol-1-yl]ethanone (25 mg).
