Procedure

The product of step E (22 mg, 0.038 mmol) was diluted with methylene chloride (1 mL) followed by the addition of TFA (1 mL). After stirring for 1 hour, the reaction was concentrated, diluted with ether, sonicated and concentrated to yield 2-(4-(4-((3,4-dichlorophenyl)carbamoyl)phenoxy)-3-(methylsulfonamidomethyl)phenyl)acetic acid (15 mg, 75% yield) as a white solid. 1H NMR (400 MHz, CDCl3/CD3OD) 7.92 (m, 1H), 7.90 (d, 2H), 7.59 (m, 1H), 7.42 (m, 2H), 7.25 (m, 1H), 7.10 (d, 2H), 6.90 (d, 1H), 4.28 (s, 2H), 3.62 (s, 2H), 2.85 (s, 3H).
