The mixture was heated under reflux, and a solution of 360 mg of 3-acetamino-1-bromopropane in 3 ml of ethanol. The reaction mixture was heated under reflux for 8 hours, and the solvent was distilled off under reduced pressure. Water was added, and the mixture was extracted with chloroform. The organic layer was dried over anhydrous magnesium sulfate, and the solvent was distilled off under reduced pressure. The residue was purified by TLC (developing solvent: chloroform/methanol=9/l) to afford 205 mg of N-[3-[3-(1-piperidinylmethyl)phenoxy]propyl]acetamide as an oil. The resulting product coincided with the product obtained in Example 2.
