実験手順
To a stirred solution of 2-bromobenzenesulfonyl chloride (Lancaster Synthesis) (2.21 g, 8.65 mmol) in chloroform (40 ml) under nitrogen at room temperature was added tert-butylamine (Aldrich) (2.30 ml, 21.9 mmol). The orange solution was stirred at room temperature for 12 hours, then the mixture evaporated to dryness. Flash chromatography (silica gel, 15% ethyl acetate-hexane) afforded the title compound, (2.12 g, 84%) as a white solid; 1H NMR (300 MHz, CDCl3) δ8.18 (d, J=8.5 Hz, 1H), 7.73 (d, J=8.5 Hz, 1H), 7.50-7.35 (m, 2H), 5.11 (s, 1H), 1.20 (s, 9H).
