Reaction Steps

7.0 g (0.05 mol) of 4-(methylthio)phenol are stirred in 80 cc of absolute dimethylformamide for 30 minutes with 2.8 g (0.05 mol) of pulverized potassium hydroxide. 16.2 g (0.075 mol) of 1,4-dibromo butane are added dropwise over the course of 15 minutes and the mixture is stirred at 20° for 16 hours. After the addition of approximately 150 cc of water, the reaction mixture is extracted with ether, the extract is washed with ice-cold 1N sodium hydroxide solution and saturated sodium chloride solution, dried over sodium sulphate and evaporated. After chromatography of the residue on silica gel with hexene/ethyl acetate (99:1) and (98:2) and subsequent crystallization from petroleum ether, pure 1-(4-bromo-butyloxy)-4-(methylthio)-benzene is obtained. M.P.: 33°-34° C.
