実験手順

Next, a solution of (S)-5-(3′-chloro-biphenyl-4-yl)-4-{[2-(4-methoxy-benzyl)-2H-tetrazole-5-carbonyl]-amino}-2-methyl-pentanoic acid ethyl ester (212 mg, 0.377 mmol) in TFA (5 mL) is stirred at room temperature for 18 hours. The solvent is removed under reduced pressure and the residue is purified by chiral HPLC on a Chirapak IA column using heptane/ethanol (80:20) (0.1% TFA) to elute the title compound; HPLC Retention time 1.59 minutes (condition C): MS 442.2 (M+1); 1 H NMR (400 MHz, DMSO-d6) δ ppm 1.05-1.10 (m, 3 H) 1.10-1.16 (m, 3 H) 1.69-1.79 (m, 1 H) 1.88 (ddd, J=13.89, 9.98, 3.92 Hz, 1 H) 2.77-2.87 (m, 1 H) 2.87-2.96 (m, 1 H) 3.91-4.05 (m, J=10.72, 7.14, 7.14, 3.66, 3.66 Hz, 2 H) 4.24 (br. s., 1 H) 6.85-6.85 (m, 0 H) 7.30 (d, J=8.34 Hz, 2 H) 7.37-7.42 (m, 1 H) 7.46 (t, J=7.83 Hz, 1 H) 7.56-7.64 (m, 3 H) 7.68 (t, J=1.77 Hz, 1 H) 9.18 (br. s., 1 H).
