Procedure

{4-[2-Benzoylamino-2-(4-phenyl-butylcarbamoyl)-vinyl]-2-benzyloxy-phenoxy}-acetic acid tert-butyl ester of Step C (80 mg, 0.13 mmol) is dissolved in ETOH (2 mL) and Pd(OH)2 (13 mg) on carbon is added. Hydrogen is applied and stirred overnight. The mixture is filtered through 0.45 μm Gelman Acrodisc and the filtrate is concentrated to oil. The oil is dissolved in TFA (2 mL). After 3 hours, the TFA is removed by evaporation. The crude material is purified by reverse phase chromatography (C18, CH3CN/H2O) to provide the title compound (compound 40), {4-[2-benzoylamino-2-(4-phenyl-butylcarbamoyl)-ethyl]-2-hydroxy-phenoxy}-acetic acid; 1H NMR (400 MHz, DMSO-d6): δ8.40 (d, 2H), 7.95 (t, 1H), 7.78 (d, 2H), 7.49 (m, 1H), 7.41 (m, 2H), 7.23 (m, 2H), 7.15 (m, 3H), 6.75 (s, 1H), 6.68 (d, 1H), 6.62 (d, 1H), 4.54 (m, 1H), 4.48 (s, 2H), 3.08 (m, 2H), 2.85 (m, 2H), 2.54 (m, 2H), 1.52 (m, 2H), 1.40 (m, 2H); MS (ES+) m/z 491 (M+1).
