Reaction Steps

A solution of (2E)-3-{2-[1-tert-butyl-5-(4-methoxyphenyl)-1H-pyrazol-4-yl]-1,3-thiazol-4-yl}-N-(tetrahydro-2H-pyran-4-ylmethyl)prop-2-enamide (46.7 mg, 0.10 mmol) and 10% palladium carbon (10 mg, 0.09 mmol) in methanol (15 mL) was stirred under 1 atm hydrogen atmosphere at room temperature for 14 hr. The catalyst was filtered off, and the filtrate was concentrated under reduced pressure. The obtained residue was purified by NH-silica gel column chromatography (solvent gradient; 0→50% ethyl acetate/hexane) and crystallized from ethyl acetate and hexane to give the title compound (26.2 mg, 0.054 mmol, 55.9%) as a white powder.
