実験手順

N-(3-chloropropyl)-N-(1-methylethyl)-3-trifluoromethylbenzenesulfonamide (23.4 g, 0.068 mol) and N-methylhomoveratrylamine (13.29 g, 0.068 mol) in xylene (250 mL) containing anhydrous potassium carbonate (4.68 g, 0.034 mol) and cesium carbonate (11.08 g, 0.034 mol) were heated and stirred for 21/2 days. The reaction was cooled, filtered and stripped to provide a gum with a small amount of crystalline material evident. Solution in diethyl ether, filtration of the small amount of solid and concentration of the filtrate provided the crude product (32.91 g). Chromatography first on dry column alumina then silica gel provided the same product as in the preceding example (11.84 g) as a gum.
