Reaction Steps

To a solution of 4-(4-methanesulfonyl-phenoxy)-piperidine (0.7 g) dissolved in THF (5 ml) and 1,2-dichloroethane (10 ml) with 1-Boc-4-piperidone (0.71 g) was added NaBH(OAc)3 (0.926 g) and acetic acid (0.18 g). After 16 hours at RT aqueous NaOH (1M). solution and dichloromethane were added and the mixture was extracted with dichloromethane. The combined organic extracts were washed with water, dried with magnesium sulfate and concentrated to leave a residue which was purified by chromatography (dichloromethane:methanol 90:10) to give the sub-title product (1.1 g; MS: APCI+(M+H) 439).
