Reaction Steps

To the aqueous solution of (R)-1-(p-chlorobenzoyl)-3-amino piperidine obtained in Example 14 (amount: 3 g), p-chlorobenzoyl chloride (0.15 g) was added. The pH of the mixture was kept from pH 8.0 to 9.0 using sodium hydroxide. The mixture was stirred at 15° C. for 3 hours, and chlorobenzene (3 ml) and sodium chloride (0.5 g) were added. The mixture was stirred at 90° C. for 10 minutes. The water layer was removed, and the solvent was evaporated under reduced pressure to obtain the title compound as yellow crystal (0.16 g, yield: 36%).
