Procedure

5.3 g (20.8 mmol) of 4-(3-acetylaminophenyl)piperidine hydrochloride was dissolved in 50 ml of N,N-dimethylformamide, and then 3.8 g (27.0 mmol) of 3-bromo-1-propanol and 8.6 g (62 mmol) of K2CO3 were added to the resulting solution, followed by treating the mixture at 60° C. for 5 hours. The reaction mixture was combined with 150 ml of water and extracted with ethylacetate (100 ml×5), and then the combined organic layer was dried over anhydrous sodium sulfate, and filtered. The solvent was removed from the filtrate under a reduced pressure, and the resulting residue was refined by silica gel column chromatography (10% methanol/CH2Cl2) to obtain 4.8 g (yield 85%) of the title compound.
