Reaction Steps

2.8 g (9 mmol) of 2-methoxy-N-(4-aminophenylsulfonyl)benzamide are suspended in 100 ml of dioxane, 0.72 g (9 mmol) of pyridine and 1.21 g (9 mmol) of cyclopentan-ecarbonyl chloride are added at 0° C., and the mixture is stirred for 2 hours at this temperature. The reaction mixture is subsequently transferred into water, and the resulting precipitate is filtered off with suction. After drying, 2.68 g (73%) of N—[4-(2-methoxy-benzoylsulfamoyl)phenyl]cyclopentanecarboxamide of melting point 202-206° C. are obtained.
