実験手順

To a solution of 3,4-dimethoxybenzenesulfonyl chloride (0.500 g, 2.11 mmol), triethylamine (0.750 mL, 5.30 mmol) in 7 mL of ethyl acetate, hexylamine (0.280 mL, 2.11 mmol) was added dropwise and the resulting solution was stirred overnight. The reaction mixture was filtered and the filtrate was washed 1N HCl (2×), dried with MgSO4, filtered and concentrated in vacuo to afford 0.480 g (75%) of N-hexyl-3,4-dimethoxybenzenesulfonamide as a white solid. 1H NMR (CDCl3, 400 MHz) δ 7.46 (m, 1H), 7.32 (m, 1H), 6.94 (m, 1H), 4.22 (m, 1H), 3.93 (s, 3H), 3.92 (s, 3H), 2.93 (q, J=6.4 Hz, 2H), 1.44 (quintet, J=6.9 Hz, 2H), 1.25 (m, 6H), 0.84 (t, J=6.9 Hz, 3H).
