To a solution of 4-benzyl-3-[2-(5-benzyloxy-4′-trifluoromethyl-biphenyl-3-yl)-4-methyl-pent-4-enoyl]-oxazolidin-2-one (6.7 g, 11.2 mmol) in MeOH (150 mL) was added 10% Pd/C (670 mg, 10 w %). The black suspension was hydrogenated at 45-45 psi overnight. The mixture was filtered through celite and the solvent was removed in vacuo to obtain relatively pure 4-benzyl-3-[2-(5-hydroxy-4′-trifluoromethyl-biphenyl-3-yl)-4-methyl-pentanoyl]-oxazolidin-2-one (5.4 g, 93%).
