Reaction Steps

0.27 g of 11-carboxymethylthio-2-(7-chloroquinolin-2-yl)methoxy-6,11-dihydrodibenz[b,e]oxepine obtained in Example 21, 0.9 g of benzenesulfonamide and 0.14 g of 4-dimethylaminopyridine and 0.11 g of 1-ethyl-3-(3-dimethylaminopropyl)carbodiimide hydrochloride dissolved in 10 ml of methylene chloride were stirred at room temperature for 7 days. After 10 ml of water and 1.13 ml of 1N-hydrochloric acid were added to the reaction mixture, the organic layer was separated, washed with water and dried over anhydrous sodium sulfate. The residue obtained by removing the solvent was applied to silica gel column chromatography to obtain 0.1 g of the title compound as light brown powder.
