Hydrazine hydrate (1:1) → 4-(Hydroxymethyl)piperidin-3-ol

Participants

Reaction Steps

To a solution of 1-benzyl-3-hydroxy-4-hydroxymethylpiperidine (7.1 g) and hydrazine monohydrate (1.56 ml) in ethanol was added 10% palladium carbon (3 g), and the resulting mixture was stirred at refluxing temperature for 5 hr. 10% Palladium carbon was filtered off and the solvent was evaporated under reduced pressure to give 4.51 g of 3-hydroxy-4-hydroxymethylpiperidine.
