Versuchsvorschrift

0.626 g of methyl 3-amino-4-(2-methoxy-phenoxy)-5-[2-(tetrahydro-pyran-2-yloxy)-ethoxy]-benzoate was dissolved in pyridine (30 ml), treated dropwise while cooling with ice with a solution of 0.593 g of 4-methylsulphanylbenzenesulphonyl chloride in toluene (10 ml) and subsequently stirred at RT for 20 hours. The reaction mixture was poured on to ice/3M HCl, the product was extracted with ethyl acetate and the organic phase was dried over magnesium sulphate. After removing the solvent there was obtained methyl 4-(2-methoxy-phenoxy)-3-(4-methylsulphanyl-benzenesulphonylamino)-5-[2-(tetrahydro-pyran-2-yloxy)-ethoxy]-benzoate as a yellow oil.
