Versuchsvorschrift

[2-(3-Amino-propylamino)-thiazol-5-yl]-o-tolyl-methanone was dissolved in dichloromethane and triethylamine and toluene-4-sulfonyl chloride added. The mixture was stirred overnight at room temperature, poured into 1 M pH4 phosphate buffer (5 ml) and extracted with dichloromethane (3×10 ml). The combined organic phases were dried over magnesium sulfate and evaporated. The oily residue was purified by column chromatography on silica gel (13:7 hexane/acetone eluant), using a small amount of dichloromethane to apply the mixture to the column. The title compound was isolated as an off-white solid. MS (m/e): 428.3 (M−H, 100%).
