反应详情

The title compound was synthesized by triturating aniline (0.5 g, 5.36 mmol), powdered sodium bicarbonate (0.9 g, 1.07 mmol) and benzene sulfonyl chloride (0.95 g, 5.36 mmol) for 10 min at rt. Then reaction mixture was stirred with water at 60° C. for 30 minutes, filtered, washed with water and dried to gave 17 (0.85 g, 68%). Product was purified by FCC by using eluent as in 15 to give 17 as white flakes (0.79 g), mp: 107-109° C. (lit33A 110° C.); IR (CHCl3) 3256, 1599, 1331, 1162, cm−1; 1H NMR (500 MHz, DMSOD6) δ 6.4 (br, 1H, NH), and 7.04-7.77 (m, 10H, aromatic). HRMS calcd 256.04027 (C12H11NO2S.Na+), found 256.04016.
