1,4-dibenzylpiperidin-4-ol → 4-Benzyl-4-piperidinol

Participants

Reaction Steps

A mixture of N-benzyl-4-benzyl-4-piperidinol (2.0 g, 7.1 mmol) and 10% palladium on charcoal catalyst (0.5 g) in absolute ethanol (100 ml), was stirred vigorously at 40° C. under a balloon of hydrogen for 5 h. The reaction mixture was then filtered through a pad of Celite and the filtrate concentrated in vacuo to a grayish solid. This material was dissolved in methanol and filtered a second time through Celite and the filtrate concentrated in vacuo to the product, a white solid.
