Versuchsvorschrift
A mixture of 1-benzyl-3,3-diethyl-4-hydroxypiperidine (3.9 g, 15.85 mmole) and 20% palladium hydroxide (1.0 g) in methanol (100 ml) was stirred at 40° C. in hydrogen atmosphere (3.5 atm.) for 6 hr. Catalyst was filtered off, washed with methanol, filtrate was concentrated to dryness to give 3,3-diethyl-4-hydroxypiperidine as oil. Yield 1.8 g (73%), C9H19NO, m/z 158 (M+1).
