Procedure
To a mixture of (3-methyl-oxetan-3-yl)-methanol (10.2 g, 0.1 mol) and DMAP (18.3 g, 0.15 mol) in DCM (100 mL) was added 4-methyl-benzenesulfonyl chloride (19 g, 0.1 mol). The mixture was stirred at room temperature for 1 h, then filtered. The filtrate was washed with HCl aq. (1 M) and water, dried over anhydrous Na2SO4 and concentrated to give the title compound (18 g).
