실험 절차

A 25% aqueous ammonium solution was added dropwise to a solution of 5-(5-chloropentanoyl)-2-methoxybenzenesulfonyl chloride (3.00 g) obtained in Reference Example 65 in tetrahydrofuran (50 ml) under ice-cooling. After stirring at room temperature for 30 minutes, the solvent was evaporated under reduced pressure, extracted with ethyl acetate, and washed with brine. The organic layer was dried over anhydrous magnesium sulfate, and the solvent was evaporated under reduced pressure to give the title compound as colorless crystals (2.54 g) having a melting point of 135 to 136° C.
