Procedure

At 10-15° C., 27 g (0.23 mol) of methanesulfonyl chloride dissolved in 20 ml of CH2Cl2 is dripped into a mixture of 34 g (0.2 mol) of 3-methyl-2-nitrobenzyl alcohol and 27 g (0.27 mol) of triethylamine in 100 ml of CH2Cl2. The reaction mixture is stirred for 1 hour at room temperature and is then extracted with water. The organic phase is dried over MgSO4 and evaporated down. There is obtained as residue 48 g of the title compound as a yellow oil, containing about 10% of the corresponding benzyl chloride as impurity. The crude product is used for the next reaction without any further purification.
