Reaction Steps

A mixture of 1-benzyl-3,5-dimethyl-3-ethyl-4-hydroxypiperidine (2.9 g, 11.74 mmole) and 20% palladium hydroxide (0.5 g) in methanol (20 ml) was stirred in hydrogen atmosphere (1 atm.) for 8 hr at 35° C. Catalyst was filtered off, washed with methanol, filtrate was concentrated to dryness to give 3,5-dimethyl-3-ethyl-4-hydroxypiperidine as oil. Yield 1.7 g (93%), C9H19NO, m/z 158 (M+1).
