Reaction Steps

HCl (conc., 1.5 mL) was slowly added to a flask containing tert-butyl 4-(3,4-dichlorophenyl)-4-hydroxypiperidine-1-carboxylate (200 mg, 0.58 mmol). The mixture was stirred at rt for 30 mins, heated to 90° C. for 5 h and then cooled overnight. The resulting precipitate was collected by filtration to give 4-(3,4-dichlorophenyl)-1,2,3,6-tetrahydropyridine hydrochloride (107 mg, 70% yield). MS found: 215.6 (M+).
