Procedure

A solution of trans-7-{[3-(3,5-bis-trifluoromethyl-phenyl)-allyl]-methanesulfonyl-amino}-heptanoic acid (210 mg, 0.44 mmol) in MeOH (10 mL) was added to 10% Pd/carbon (200 mg). The mixture was placed on a Parr hydrogenator at 50 psi and was hydrogenated for 20 h. The reaction was filtered through Celite with the aid of MeOH and the solvent was removed in vacuo. Purification by radial chromatography (2 mm rotary plate, 20:80:0.1 v/v/v EtOAc/hexanes/AcOH) provided the title compound (190 mg). 1H NMR (CDCl3 400 MHz) 87.69 (s, 1H), 7.63 (s, 2H), 3.20 (t, 2H), 3.14 (t, 2H), 2.81 (m, 5H), 2.28 (m, 2H), 1.94 (m, 2H), 1.32 (m, 4H); MS 495 (M+18).
