実験手順
To a solution of TFA/DCM (1:3, 10 mL) was added intermediate 31 (150 mg, 0.26 mmol, 1 eq) and the mixture was stirred at room temperature for 2 h. The organic solvent was removed in vacuo and the crude product was purified by reversed phase semi-preparative HPLC to afford 100 mg (73%) of 2-((4-fluoro-3-(methylsulfonyl)phenyl)-4-((4-fluoro-N-methylphenylsulfonamido)methyl)phenoxy)acetic acid (Example 28). 1HNMR (CD3CN, 300 MHz): δ 8.08 (m, 1H), 7.95 (m, 1H), 7.88 (m, 2H), 7.26-7.44 (m, 5H), 7.00 (d, 1H), 4.71 (s, 2H), 4.18 (s, 2H), 3.25 (s, 3H), 2.55 (d, 3H). MS (ES-API): MH−=524.1. HPLC (Method A) tR=2.02 min.
