Versuchsvorschrift
A balloon filled with hydrogen was charged into a solution of 4-(3,4-dichlorophenyl)-1,2,3,6-tetrahydropyridine hydrochloride (107 mg, 0.41 mmol) in the presence of 5% Pd/C (5% mmol) after the system was degassed. The reaction was stirred at rt for 2 h, filtered, rinsed with MeOH and then concentrated to give 4-(3,4-Dichlorophenyl)piperidine hydrochloride (79 mg, 72% yield) as an oil. MS found: 266.4 (M+).
