Procedure
Under a hydrogen atmosphere, a mixture of N-[(1S)-2-({1-benzyl-5-[6-(cyclopropylmethoxy)-1,3-benzoxazol-2-yl]-1H-pyrazol-3-yl}oxy)-1-methylethyl]acetamide (120 mg), 20% palladium hydroxide/carbon (containing water (50%), 60 mg), ethanol (5 mL) and THF (3 mL) was stirred at 50° C. for 4 hr. The catalyst was removed by filtration, and the obtained filtrate was concentrated under reduced pressure. The residue was purified by silica gel column chromatography (hexane/ethyl acetate) to give the title compound (23.4 mg).
