Procedure

To a solution of 5-fluoro-2-methyl-benzenesulfonyl chloride (4.18 g, 20 mmol) in tetrahydrofuran (25 mL) was added, dropwise, a solution of dimethylamine in tetrahydrofuran (2M, 25 mL, 50 mmol) over 15 min. and the mixture stirred for 5 min. The insoluble materials were filtered and the filtrate concentrated. The residue was purified by column chromatography (SiO2, 5% ether in CH2Cl2) to provide 4.3 g (Yield 90%) of the title compound as a clear oil: 1H NMR (500 MHz, CDCl3) δ ppm: 2.57 (3H, s) 2.82 (3H, s) 2.82 (3H, s) 7.12–7.18 (1H, m) 7.28 (1H, dd, J=8.2, 5.5 Hz) 7.59 (1H, dd, J=8.2, 2.1 Hz); LC/MC m/z 218 (M+H).
