実験手順
The reaction and aftertreatment were conducted in the same manner as in Example 106b by using the 3-[(1R,2S)-2-(benzyloxy)cyclopentyl]-1-(tetrahydro-2H-pyran-2-yl)-1H-pyrazole (403 mg, 1.23 mmol) prepared in Example 148d, palladium carbon (5%; 400 mg) and ethanol (20 mL) to yield the title compound (265 mg, 91%) in the form of a diastereomeric mixture as a colorless oil.
