Versuchsvorschrift
A mixture of 1-benzyl-4-hydroxy-3-trifluoromethylpiperidine (1.8 g, 6.94 mmole and 20% palladium hydroxide (0.5 g) in methanol (25 ml) was stirred in hydrogen atmosphere (1.atm.) for 17 hr at 50° C. Catalyst was filtered off, washed with methanol, filtrate was concentrated to dryness to give 4-hydroxy-3-trifluoromethylpiperidine as oil. Yield 0.7 g (60%), C6H10F3NO, m/z 170 (M+1).
