Reaction Steps

A mixture of N-[(1-{[1-(2-benzyl-2H-tetrazol-5-yl)cyclopentyl]methyl}piperidin-4-yl)methyl]-2′-oxospiro[cyclopentane-1,3′-indole]-1′(2′H)-carboxamide (120 mg, 0.21 mmol, step 6 of Example 14) and palladium hydroxide (20 mg, 20 wt. % palladium on carbon) in methanol (10 mL) was stirred for 8 h under H2 atmosphere. The mixture was filtered through a pad of Celite, and washed with methanol and the filtrate was concentrated to give a clear colorless oil. The residue was chromatographed on a column of silica gel eluting with CH2Cl2/methanol (16:1) to give 80 mg (80%) of the title compound as a white solid. The solid was triturated with ethyl acetate/hexane and collected by filtration to give 72 mg (72%) of the title compound as a white solid.
