실험 절차
2-[4-(2-Piperidin-1-yl-ethoxy)-phenyl]-ethanol (4.23 g, 16.98 mmol) was dissolved in 200 ml of THF. HCl gas was bubbled through the solution at 0° C. for 5 minutes. Still at 0° C. the thionyl chloride (2.48 ml, 33.9 mmol) was added dropwise. The reaction mixture was heated at reflux for 2 hours before it was concentrated. 1-{2-[4-(Chloro-ethyl)-phenoxy]-ethyl}-piperidine (4.74 g, 15.6 mmol) was isolated as a brown semisolid; Yield 92%; MS: 268.3 (M+H)+
