الإجراء التجريبي

To a solution of 1,4-dimethylsulphonyl-2-butene (2.15 g, 11.64 mmol) in dichloromethane (40 ml), 4-methoxybenzylamine (6 ml, 44.24 mmol) was added dropwise and the solution was stirred 20 hours at r.t. The solid was filtrated and the filtrate was washed with water (2×30 ml), dried over Na2SO4, filtered and concentrated. The crude was purified by flash chromatography: silica gel, gradient hexane:ethyl acetate 3:1 to 1:1. to afforded the product (1.4 g, 63%) as yellow oil.
