Versuchsvorschrift
A suspension of 6.48 g (25.00 mmol) of 1-benzyl-4-trifluoromethylpiperidin-4-ol and 810 mg Pd/C (10%) in 100 mL of MeOH was hydrogenated at RT and 3 bar hydrogen pressure for 17 hours. The catalyst was filtered off and the filtrate evaporated down in vacuo. Yield: 4.22 g (quant. yield); C6H10F3NO (M=169.145); calc.: molpeak (M+H)+: 170; found: molpeak (M+H)+: 17; Rf value: 0.00 (silica gel, cyc/EtOAc 2:1).
