Versuchsvorschrift

In a stream of nitrogen and at 0° C., 0.16 ml (1.10 mmol) of hexanoyl chloride was added to an anhydrous tetrahydrofuran (10 ml) solution containing 390 mg (1.00 mmol) of 3-heptyloxy-N-(2-sulfamoylphenyl)benzamide produced in Reference Example 9 and 249 mg (2.00 mmol) of 4-dimethylaminopyridine, the mixture was stirred at room temperature for 1 hour and then the solvent was evaporated under a reduced pressure. The resulting residue was dissolved in ethyl acetate, washed with water, a potassium hydrgensulfate aqueous solution and saturated brine in that order and dried over anhydrous sodium sulfate, and then the solvent was evaporated under a reduced pressure. The resulting residue was purified by a silica gel column chromatography to obtain 412 mg (yield: 84.4%) of the title compound.
