Reaction Steps

19 g of 4-amino-1-benzylpiperidine are placed in 50 ml of 1,2-dichloroethane under dry nitrogen and 10 g of tetrahydropyran-4-one in 20 ml of 1,2-dichloro-ethane are added; after stirring for 10 minutes, 29.6 g of NaBH(OAc)3 are added and the mixture is then stirred for one day. 10% Na2CO3 solution and EtOAc are added to the reaction medium and the phases are then separated by settling. The organic phase is washed with 10% Na2CO3 solution and then with saturated NaCl solution, and then dried over MgSO4 and evaporated under vacuum. 23.4 g of the expected compound are obtained. m.p.=60° C.
