실험 절차

4-(3,4-Dichlorophenoxy)piperidine (1.5 g) was dissolved in 1,2-dichloroethane (21 ml). 1-Boc-4-piperidone was added (1.21 g) followed by NaBH(OAc)3 (1.81 g) and acetic acid (0.37 g). After 18 hours at room temperature aqueous NaOH (1M) solution and diethyl ether were added. The product was extracted with diethyl ether, the combined organic extracts dried with MgSO4 and concentrated. Purification by silica chromatography (dichloromethane:methanol 92:8) gave the sub-title product (1.97 g).
