Product 1

HCID 2304564779412-27-4Yield 86%

Procedure

N-Propyl-3-(3-methoxyphenyl)piperidine hydrochloride (7.0 g, 0.026 mol) was suspended in 48% HBr (200 ml). The mixture was refluxed under nitrogen for 3 h. The hydrobromic acid was evaporated and the residue was recrystallized from ethanol/ether, yielding the pure product (6.7 g, 86%) mp. 146°-7.5° C.
