Analogously to Example 77, by condensing methyl 3-amino-4-(2-chloro-5-methoxy-phenoxy)-5-[2-(tetrahydro-pyran-2-yloxy)-ethoxy]-benzoate with benzo[1,3]dioxol-5-sulphonyl chloride there was obtained methyl 3-(benzo[1,3]dioxol-5-sulphonylamino)-4-(2-chloro-5-methoxy-phenoxy)-5-[2-(tetrahydro-pyran-2-yloxy)-ethoxy]-benzoate und therefrom by treatment with 5.5M HCl there was obtained methyl 3-(benzo[1,3]dioxol-5-sulphonylamino)-4-(2-chloro-5-methoxy-phenoxy)-5-(2-hydroxy-ethoxy)-benzoate.
