Procedure
3-Chloro-4-nitrobenzenesulphonamide (1.08 g; 4.53 mmol), 4-chlorothiophenol (0.66 g; 4.53 mmol) and K2CO3 (0.64 g; 4.60 mmol) were refluxed in dioxan (30 ml) for 3 hours. The mixture was then diluted with CH2Cl2, filtered and washed with water. The organic phase was dried over MgSO4 and evaporated down. The product was recrystallised from petroleum ether/ethyl acetate. Yield: 1.0 g=64% 13C (100 MHz, DMSO-d6) δ 148.57, 146.43, 138.07, 137.08, 135.76, 130.70, 128.74, 127.27, 125.43, 123.52
