Procedure

There was dissolved 2.07 g (0.011 mol) of 2-[2-(methoxycarbonylamino)ethylthio]acetic acid in 50 ml of dichloromethane and added 1.68 g (0.011 mol) of HOBt and 2.27 g (0.011 mol) of DCC under cooling with ice, and the mixture was stirred for 30 minutes under cooling with ice. Thereto was added 2.7 g (0.011 mol) of 3-[3-(piperidinomethyl)phenoxy]propylamine and the mixture was stirred for 18 hours at room temperature. The precipitate was filtrated off, and the filtrate was washed with 5% aqueous solution of sodium hydroxide and with water and dried over Glauber's salt. Then the solvent was removed under reduced pressure and the residue was purified by silica gel column chromatography (chloroform:methanol=5:1) to give 3.69 g of the titled compound as oily matter.
