Procedure
Methanesulfonyl chloride (Compound 19, 2.6 ml, 34.0 mmol) was added to a mixture of N,N-dimethylethylenediamine (3.7 ml, 34.0 mmol) and diisopropylethylamine (5.93 ml, 34.0 mmol) in tetrahydrofuran (30 ml) at 0° C. After 1.5 hours stirring at 0°, the mixture was quenched with water and extracted thoroughly with ethyl acetate. Evaporation of the dried (magnesium sulfate) extract gave an oil, which was purified by flash chromatography on silica using 20% methanol/chloroform to give the title sulfonamide. 1HNMR(CDCl3): 2.24 (s, 6H), 2.48 (t, 2H, J=5.9 Hz), 2.97 (s, 3H), 3.18 (t, 2H, J=5.6 Hz). 13CNMR(CDCl3): 39.3, 39.9, 44.5 and 57.8.
