Analogously to Example 77, by condensing methyl 3-amino-4-(2-chloro-5-methoxy-phenoxy)-5-[2-(tetrahydro-pyran-2-yloxy)-ethoxy]-benzoate with 4-(trifluoromethyl)-benzenesulphonyl chloride there was obtained methyl 4-(2-chloro-5-methoxy-phenoxy)-3-[2-(tetrahydro-pyran-2-yloxy)-ethoxy]-5-(4-trifluoromethyl-benzenesulphonylamino)-benzoate and therefrom by treatment with 5.5M HCl there was obtained methyl 4-(2-chloro-5-methoxy-phenoxy)-3-(2-hydroxy-ethoxy)-5-(4-trifluoromethyl-benzenesulphonylamino)-benzoate.
