Reaktionsschritte

4-Methoxyphenylsulfamoyl chloride (11.0 g, crude from Step B) in acetonitrile (5.0 mL) was added to a mixture of trimethyl(prop-1-en-2-yloxy)silane (0.85 g, 85% purity, 5.56 mmol) and triethylamine (2.0 mL) in acetonitrile (10 mL) at rt. Upon addition, the reaction was warmed up and refluxed for 2 hrs. After cooling to rt., solvent was removed under reduced pressure and product was purified by flash chromatography (silica gel, ethyl acetate/hexanes gradient) to give N-(4-methoxyphenyl)-2-oxopropane-1-sulfonamide as a solid. LC-MS found: (M+1)+=244.2.
