실험 절차

To the product of Step A was added ethanol (6.4 mL) followed by a solution of NaOH (0.483 g, 12.1 mmol) in water (6.4 mL). The reaction was stirred at ambient temperature for 1 hour. To the mixture was added 1 NHCl (22.8 mL), and the mixture stirred at ambient temperature overnight. The solids were collected by filtration, washed with water (2×4 mL) and dried in a vacuum oven at 45° C. overnights to give 3-{[(3-fluorophenyl)amino]sulfonyl}benzoic acid: 1H NMR (400 MHz, DMSO-d6) δ ppm 13.51 (bs, 1H), 10.68 (bs, 1H), 8.30 (t, J=1.8, 1H), 8.14 (dt, J=7.7, 1.4, 1H), 7.99 (ddd, J=7.8, 2.0, 1.1, 1H), 7.70 (t, J=7.8, 1H), 7.27 (m, 1H), 6.94-6.82 (m, 3H); MS (ESI) m/z 294 (M−H)−.
