Participants

Reaction Steps

Methyl 2-(4-(4-(3,4-dichlorobenzamido)phenoxy)-3-((4-fluorophenyl-sulfonamido)methyl)phenyl)acetate (40 mg, 0.065 mmol) was diluted with MeOH (1 mL) followed by the addition of NaOH (0.32 mL, 1.3 mmol). After stirring for 1 hour, the reaction mixture 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 0.5 mm preparative plate eluting with methylene chloride:MeOH:AcOH (90:9:1) to yield 12 mg of the title compound as a solid. 1H NMR (400 MHz, CDCl3/CD3OD) 8.1 (m, 1H), 7.85 (m, 1H), 7.8 (m, 2H), 7.7 (d, 1H), 7.6 (d, 1H), 7.25 (s, 1H), 7.2 (m, 3H), 6.85 (d, 2H), 6.7 (d, 1H), 4.15 (s, 2H), 3.55 (s, 2H).
