Versuchsvorschrift

A solution of [5-fluoro-7-(methylsulfonyl)-2,3-dihydro-1,4-benzodioxin-2-yl]methanol (0.4 g, 1.7 mmol), toluenesulfonyl chloride (0.5 g, 2.6 mmol), TEA (0.4 ml, 2.6 mmol) and 4-DMAP (0.2 g, 1.7 mmol) in DCM (10 ml) was stirred at rt for 1 h. DCM was added and the resulting mixture was washed with HCl (1 N) and brine. The organic phase was dried (Na2SO4) and evaporated to dryness to give the title compound (0.7 g). MS m/z (rel. intensity, 70 eV) 416 (M+, 31), 244 (bp), 243 (26), 231 (19), 91 (70).
