实验步骤: In a sulfonating flask, 50 g (0.32 mol) of 4-methylthiobenzyl alcohol and 46.3 g (0.32 mol) of methylsulfonyl chloride are dissolved in 250 ml of toluene and, with cooling at 10° C., 32.5 g (0.32 mol) of triethylamine are added dropwise. The reaction mixture is then heated to room temperature and stirred overnight. 400 ml of 2N hydrochloric acid are then added to the reaction solution slowly and with cooling. The phases are separated and the organic phase is washed with water, dried over MgSO4 and concentrated in a rotary evaporator. 60 g (80%) of 4-methylthiobenzyl alcohol methanesulfonate are obtained in the form of a yellow oil. The reaction mixture is then heated to room temperature with cooling The phases are separated the organic phase is washed with water dried over MgSO4 concentrated in a rotary evaporator

实验步骤: 4-Methylsulfanylbenzyl alcohol (30.5 g; 0.2 mol) was dissolved in dichloromethane (180 ml). A solution of thionyl chloride (23.8 g; 0.2 mol) in dichloromethane (120 ml) was added dropwise to the initial charge, which was kept under reflux. The reaction mixture was stirred under reflux for a further 2 h. The solution was cooled to room temperature, washed with H2O (2×250 ml), dried over Na2SO4 and concentrated. The oily residue (6) was purified by column chromatography (Al2O3, CH2Cl2). initial charge under reflux under reflux for a further 2 h washed with H2O (2×250 ml) dried over Na2SO4 concentrated The oily residue (6) was purified by column chromatography (Al2O3, CH2Cl2)
