Versuchsvorschrift

135 mg of methyl 3-amino-4-(2-chloro-5-methoxy-phenoxy)-5-[2-(tetrahydro-pyran-2-yloxy)-ethoxy]-benzoate were dissolved in pyridine (3 ml), treated while cooling with ice with a solution of 111 mg of 4-methoxy-benzenesulphonyl chloride in toluene (1 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 washed with water and dried over magnesium sulphate. After removing the solvent there was obtained methyl 4-(2-chloro-5-methoxy-phenoxy)-3-(4-methoxy-benzenesulphonylamino)-5-[2-(tetrahydro-pyran-2-yloxy)-ethoxy]-benzoate as a foam.
