Procedure

To a solution of 2-(4-fluoro-2-methoxy-phenoxy)-4-(1,1,2,2,2-pentafluoroethyl)benzoic acid (152.1 mg, 0.10 mmol), tert-butyl 4-aminobenzoate (21.26 mg, 0.11 mmol) and HATU (41.83 mg, 0.11 mmol) in DMF (0.5 mL) was added N-methylmorpholine (24.18 μL, 0.22 mmol) and the mixture was stirred at 25° C. for 16 hours. The mixture was poured into water and extracted with ethyl acetate (3×). The organics were combined, evaporated and taken up in dichloromethane (0.25 mL). TFA (0.25 mL, 3.245 mmol) was added and the reaction mixture was stirred at 25° C. for 1 h. The mixture was diluted with MeOH, filtered and purified by reverse phase HPLC using a gradient of acetonitrile in water (1-99%) containing HCl as a modifier to give 4-[[2-(4-fluoro-2-methoxy-phenoxy)-4-(1,1,2,2,2-pentafluoroethyl)benzoyl]amino]benzoic acid (27) (5.16 mg, 10%) as a white solid. ESI-MS m/z calc. 499.07, found 500.3 (M+1)+; Retention time: 1.82 minutes (3 minutes run). 1H NMR (400 MHz, DMSO) δ 12.80 (s, 1H), 10.84 (s, 1H), 7.94 (d, J=8.6 Hz, 2H), 7.87 (d, J=8.0 Hz, 1H), 7.83 (d, J=8.8 Hz, 2H), 7.52 (d, J=7.9 Hz, 1H), 7.40-7.27 (m, 1H), 7.16 (dd, J=10.6, 2.8 Hz, 1H), 6.98-6.82 (m, 1H), 6.77 (s, 1H), 3.73 (s, 3H) ppm.
