To a solution of compound 39a, 2-[5-(1-Methanesulfonyl-piperidin-3-yl)-4′-trifluoromethyl-biphenyl-3-yl]-4-methyl-pentanoic acid ethyl ester (70.0 mg, 0.133 mmol) in EtOH (6.5 ml) was added 2M KOH (0.027 ml, 0.53 mmol). The reaction was heated to 78° C. for 3 hours, cooled to room temperature, and concentrated in vacuo. Purification via Gilson HPLC, gave the product as a white lyophilate.
