Procedure
A mixture of N4-(2,3-dihydroxypropyl)sulfanilamide (82 mg, 0.33 mmol), 1-chloro-2-nitro-4-trifluoromethanesulfonyl-benzene (135 mg, 0.47 mmol) and potasium carbonate (190 mg, 1.33 mmol) in acetonitrile (2 mL) was heated to reflux for 2 days. The reaction was diluted with chloroform/isopropanol mixture, washed with brine, dried, concentrated and column chromatographed to give the title compound (mono-arylated) and 4-[2,3-bis-(2-nitro-4-trifluoromethanesulfonyl-phenoxy)-propylamino]-benzenesulfonamide (di-arylated) example 62. 1H NMR (300 MHz, DMSO-d6) δ 8.63 (d, 1H), 8.35 (dd, 1H), 7.75 (d, 1H), 7.63 (d, 2H), 6.68 (d, 2H), 4.35 (d, 2H), 3.98 (t, 1H), 3.2 (m, 2H). MS −ve APCI 498 [M−1].
