A solution of the 5-[(1S,6S)-4,4-difluoro-7-oxabicyclo[4.1.0]hept-1-yl]-1-methyl-1H-pyrazole (50 mg, 0.233 mmol) prepared in Example 102b and Raney nickel (500 mg) in isopropanol (20 mL) was stirred for 3 hours under a hydrogen atmosphere. The reaction solution was filtered, the filtrate was concentrated, and the residue was then purified with silica gel chromatography to yield the title compound (21.2 mg, 42%) as a colorless oil.
