Versuchsvorschrift

To 6 N HCl (30 mL) was added a solution of intermediate 46 (5.2 g, 14 mmol) in THF (10 mL). The mixture was heated to reflux for 3 h and then concentrated in vacuo. The residue was washed with Et2O to give 4-(2,3-dichlorophenyl)piperidine (intermediate 47) (3.5 g, 92%) as a white solid. HPLC: 99%, RT 2.149 min. MS (ESI) m/z 230.1 [M+H]+
