Reaction Steps

10% Palladium on carbon (59 mg, 0.55 mmol) was added to a stirred ethanol (5.5 mL) solution of (1R)-2-(benzyloxy)-1-methyl-2-oxoethyl 2-butyl-4-chloro-1-{[2′-(1H-tetrazol-5-yl)biphenyl-4-yl]methyl}-1H-imidazole-5-carboxylate (332 mg, 0.55 mmol). The mixture was stirred under hydrogen for 2 hours. The mixture was filtered through Celite, and the filtrate was concentrated in vacuo to give the title compound as a white solid. 1H NMR (500 MHz, CDCl3) δ 7.67-7.62 (m, 2H), 7.56-7.50 (m, 2H), 7.09 (d, J=8.0 Hz, 2H), 7.01 (d, J=8.0 Hz, 2H), 5.67 (d, J=16.5 Hz, 1H), 5.57 (d, J=16.5 Hz, 1H), 5.15 (q, J=6.5 Hz, 1H), 2.65 (t, J=7.5 Hz, 2H), 1.56 (quintet, J=7.5 Hz, 2H), 1.49 (d, J=7.0 Hz, 3H), 1.31 (sextet, J=7.5 Hz, 2H), 0.87 (t, J=7.5 Hz, 3H); LC-MS: m/z 509.2 (M+H).
