実験手順

To the product of Step A was added ethanol (8 mL) followed by a solution of NaOH (0.483 g, 12.06 mmol) in water (8 mL). The reaction was stirred at ambient temperature for 45 minutes. To the mixture was added 1 N HCl (23 mL) and the mixture was stirred overnight. The solids were collected by filtration, washed with water (1×5 mL) and dried by vacuum filtration to give 3-{[(2-fluorophenyl)amino]sulfonyl}benzoic acid: 1H-NMR: (400 MHz, DMSO-d6) δ ppm 13.97 (bs, 1H), 10.62 (bs, 1H), 8.26 (dd, 1H, J=1.6, 1.6, 3.2 Hz), 8.16 (ddd, 1H, J=8.1, 1.1, 1.1 Hz), 7.90 (ddd, 1H, J=8.1, 1.4, 1.4 Hz), 7.68 (dd, 1H, J=7.8, 7.8 Hz), 7.25-7.1 (m, 4H); MS (ESI) m/z 294.2 (M−H)−.
