Ethyl 2-(6-(4-(4-chlorophenethylcarbamoyl)phenoxy)-3′-(methylsulfonyl)biphenyl-3-yl)acetate (80 mg, 0.135 mmol) was diluted with dioxane (1 mL) followed by the addition of NaOH (0.270 ml, 1.35 mmol) and 300 μL of water. After stirring for 2 hours, the reaction was diluted with ethyl acetate and 2N HCl. The layers were separated and the organic layer was dried over MgSO4, filtered and concentrated. The material was purified using a biotage 12i cartridge eluting with 1-4% methanol/DCM to yield 2-(6-(4-(4-chlorophenethylcarbamoyl)phenoxy)-3′-(methylsulfonyl)biphenyl-3-yl)acetic acid (5 mg, 6.56% yield). 1H NMR (400 MHz, CD3Cl3, CD3OD) 8.05 (s, 1H), 7.81 (d, 1H), 7.78 (d, 1H), 7.50-7.60 (m, 3H), 7.42 (s, 1H), 7.38 (d, 1H), 7.25 (d, 2H), 7.19 (d, 2H), 7.05 (d, 1H), 6.85 (d, 1H), 3.75 (s, 2H), 3.62 (q, 2H), 3.0 (s, 3H), 2.90 (t, 2H).
