Procedure

A mixture of (2R,4S)-4-[(1-benzyl-1H-tetrazole-5-carbonyl)-amino]-5-biphenyl-4-yl-2-methyl-pentanoic acid benzyl ester and (2R,4S)-4-[(2-benzyl-2H-tetrazole-5-carbonyl)-amino]-5-biphenyl-4-yl-2-methyl-pentanoic acid benzyl ester (126 mg, 0.225 mmol) in MeOH is hydrogenated with 10% Pd/C for 6 h. The reaction mixture is concentrated and purified by reverse phase HPLC to give (2R,4S)-5-biphenyl-4-yl-2-methyl-4-[(1H-tetrazole-5-carbonyl)-amino]-pentanoic acid. HPLC Retention time 1.16 minutes (condition D); MS 380.0 (M+1);
