실험 절차
0.50 g (1.29 mmol) of 4-[4-[(4-chlorophenyl)-2-pyridylmethoxy]-1-piperidyl]butanoic acid obtained in Example 28 was dissolved in 5 ml of dichloromethane, and 0.32 g (1.55 mmol) of dicyclohexylcarbodiimide was added to the reaction mixture on an ice bath. Then, 10 ml of ammonia gas dissolved dichloromethane solution was added, and the mixture was stirred at room temperature for 10 hours. After the reaction, the insolubles were filtered off, and the filtrate was concentrated under reduced pressure. The residue was separated by silica gel column chromatography using a mixture of chloroform, methanol and conc. ammonia water (conc. 25% by weight) in the volume ratio 90:9:1 as the eluent. The desired fraction was concentrated under reduced pressure to give 0.38 g (76%) of 4-[4-[(4-chlorophenyl)-2-pyridylmethoxy]-1-piperidyl]butanamide as an oil.
