5-Bromo-2-heptyloxy-benzoic acid (0.231 g, 0.738 mmol) and the (2S)-Amino-3-(2′-hydroxy-biphenyl-4-yl)-propionic acid methyl ester (0.200 g, 0.738 mmol) were then combined as per general procedure A with HBTU (0.335 g, 0.885 mmol) and diisopropylethylamine (0.285 g, 2.21 mmol) to yield the (2S)-(5-Bromo-2-heptyloxy-benzoylamino)-3-(2′-hydroxy-biphenyl-4-yl)-propionic acid methyl ester (0.200 g). The methyl ester of the title compound was the prepared from (2S)-(5-Bromo-2-heptyloxy-benzoylamino)-3-(2′-hydroxy-biphenyl-4-yl)-propionic acid methyl ester (0.080 g, 0.140 mmol) and the trifluoromethylboronic acid (0.050 g, 0.281 mmol) as per general procedure F, which was further hydrolyzed as per general procedure C to give the title compound (0.020 g). 1H-NMR(400 MHz, CDCl3): 1.14(t, 3H), 1.53 (m, 8H), 1.92(m, 2H), 3.6(m, 2H), 4.21(m, 2H), 5.21(m, 1H), 7.12(d, 1H), 7.22(m, 2H), 7.36(d, 1H), 7.5(d, 2H), 7.58(m, 2H), 7.66(m, 1H), 7.78 (m, 6H), 8.62 (S, 1H), 8.9 (bs, 1H).
