実験手順

N-isopropyl-3-trifluoromethylbenzenesulfonamide (5.362 g, 0.02 mol) in dimethylformamide (30 mL) was treated with sodium hydride (60% in mineral oil), (0.802 g) and stirred for 2 hours. Then N-(3-chloropropyl)-3,4-dimethoxy-N-methylphenethylamine (5.436 g, 0.02 mol) was added and the reaction heated overnight. Filtration and removal of solvent provided the crude product (6.95 g). Column chromatography and high pressure liquid chromatography provided the pure product (4.35 g) as a gum. 1H NMR (CDCl3) 1.15 (d, 6, J=3.5H, Me2) 2.25 (s, 3, N--Me) 3.84 (d, 6, (OMe)2) 6.76 (m, 3, Ar) 7.25 (m, 3, Ar).
