Procedure

Ethyl 2-(4-(4-((4-chlorophenethyl)carbamoyl)phenoxy)-3-(thiophen-2-yl)phenyl)acetate (20 mg, 0.038 mmol) was diluted with dioxane (500 μL) followed by the addition of NaOH (0.052 ml, 0.26 mmol) and 200 μL of water. After stirring for 3 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 to yield 2-(4-(4-((4-chlorophenethyl)carbamoyl)phenoxy)-3-(thiophen-2-yl)phenyl)acetic acid (7 mg, 37% yield) as a white solid. 1H NMR (400 MHz, CD3Cl3, CD3OD) 7.69 (s, 1H), 7.64 (d, 2H), 7.45 (d, 1H), 7.30 (d, 2H), 7.22 (d, 1H), 7.15 (d, 2H), 6.98-7.05 (m, 2H), 6.90 (d, 2H), 3.65 (m, 4H), 2.90 (t, 2H).
