実験手順

In a stream of nitrogen and at 0° C., 0.10 ml (0.96 mmol) of 2,4-hexadienoyl chloride was added to an anhydrous tetrahydrofuran (10 ml) solution containing 300 mg (0.80 mmol) of 4-phenylethynyl-N-(2-sulfamoylphenyl)benzamide produced in Reference Example 10 and 195 mg (1.60 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 thus formed crude crystals were recrystallized from methanol to obtain 180 mg (yield: 48.0%) of the title compound.
