Procedure

A mixture consisting of 4-[2-(4-Benzofuran-2-ylphenylcarbamoyl)-3-(4-cyclohex-1-enylphenyl)-propyl]-benzoic acid from step f above, EDC (101 mg, 0.53 mmol), HOBT hydrate (80 mg, 0.53 mmol), taurine (66 mg, 0.53 mmol) and diisopropyl diethylamine (0.18 mL, 1.1 mmol) in DMF (10 mL) was stirred at RT overnight. The solvent was removed under vacuum and 1N HCl was added. The resulting precipitate was filtered, washed with water and purified by preparatory HPLC on a Shimadzu modular HPLC system using a Waters Atlantis dC18 30×75 mm preparatory column and running a gradient from 40% to 100% acetonitrile over 13 minutes. TFA was used as an ionizer and was present in 0.05% (v/v). Detection was accomplished using an in-line UV detector running at 254 nm. Rotary evaporation of the solvated compound provided the title compound (50 mg): 1H NMR (300 MHz, DMSO-d6): δ 9.94 (s, 1H), 8.43 (t, J=6.12 Hz, 1H), 7.80 (d, J=8.4 Hz, 2H), 7.69 (d, J=8.4 Hz, 2H) 7.64-7.21 (m, 11H), 7.15 (d, J=8.4 Hz, 2H), 3.48 (dd, J=12.6 Hz, J=6.3 Hz, 2H), 3.1-2.9 (m, 3H), 2.8-2.4 (m, 4H), 2.38 (s, 1H), 2.35-2.25 (br m, 2H), 2.19-2.09 (br m, 2H), 1.77-1.67 (br m, 2H), 1.6-1.5 (br m, 2H). LC-MS m/z=661 [C349H38N2O6S+H]−.
