실험 절차

A mixture of 4-[(4-fluorophenyl)sulfonyl]phenylamine (IV, Step II, 3.10 g, 12.3 mmol) in concentrated hydrochloric acid (30 mL) at 0° is treated with sodium nitrite (934 mg, 13.5 mmol) in H2O (15 mL). After 30 min, the mixture is treated with stannous chloride (5.57 g, 24.7 mmol) in concentrated hydrochloric acid (15 mL). The mixture is stirred at 0° for 1 hr, and then at 20–25° for 1 hr. The precipitate is collected and slurried in H2O. The mixture is made basic (sodium hydroxide, 50%) and the solid isolated. The material is partitioned between methylene chloride and saline. The organic layer is dried, filtered, and concentrated under reduced pressure to give the title compound, NMR (300 MHz, CDCl3) 7.85–7.95, 7.74, 7.13, 6.85, 5.64 and 3.65 δ.
