実験手順
4-Acetylaminobenzenesulfonyl chloride is introduced into dichloromethane and treated at room temperature with two equivalents of N,N-dimethylethylenediamine and stirred at room temperature until complete conversion can be determined (LCMS). For work-up, the solvent is distilled off, the oily residue is taken up in dichloromethane or ethyl acetate and the mixture is washed with NaHCO3 solution. The phases are separated and the aqueous phase is extracted once more with dichloromethane or ethyl acetate. The organic phases are dried using Na2SO4 and concentrated. The crude product thus obtained is reacted further without further purification. (MS-CI+: 286.0; LCMS Rt=2.542 min)
