Ethyl 2-(4-(4-((4-chlorophenethyl)carbamoyl)phenoxy)-3-ethylphenyl)acetate (10 mg, 0.0215 mmol) was diluted with dioxane (500 μL) followed by the addition of NaOH (0.0429 ml, 0.215 mmol) and 5 drops of water. After stirring for 3 hours, the reaction was diluted with ethyl acetate and 2N HCl, and the layers were separated. The organic layer was dried over MgSO4, filtered and concentrated. The crude material was purified by silica gel chromatography eluting with 10% MeOH/DCM to yield 2-(4-(4-((4-chlorophenethyl)carbamoyl)phenoxy)-3-ethylphenyl)acetic acid (2 mg, 21.3% yield). (400 MHz, CD3Cl3, CD3OD) 7.65 (d, 2H), 7.30 (d, 2H), 7.10-7.25 (m, 4H), 6.90 (m, 3H), 3.62 (m, 2H), 3.40 (s, 1H), 2.90 (t, 2H), 2.55 (q, 2H), 1.15 (t, 3H).
