Procedure
To the aqueous solution of (R)-1-(p-chlorobenzoyl)-3-amino piperidine obtained in Example 14 (amount: 3 g), p-Methylbenzoyl chloride (0.16 g) was added. The pH of the mixture was kept from 8.0 to 9.0 using sodium hydroxide. The mixture was stirred at 15° C. for 3 hours, and the precipitated crystal was filtered off. The crystal was dried under reduced pressure to obtain the title compound as white crystal (0.28 g, yield: 66%).
