Ammonium formate → (7R,8aS)-octahydropyrrolo[1,2-a]piperazin-7-ol

Participants

Reaction Steps

A solution of 9.75 g (42.0 mmol) of (7R,8aS)-7-hydroxy-2-phenylmethyl-1,2,3,4,6,7,8,8a-octahydro-pyrrolo[1,2-a]pyrazine (Diafi, L.; et al. J. Het. Chem., 1990, 27, 2181) and 29.4 mL of 5M ammonium formate in 140 mL of methanol was treated with an aqueous slurry of 4.9 g of 10% palladium on carbon and the mixture was stirred at ambient temperature for 18 h. The mixture was filtered through Celite and evaporated to give (7R,8aS)-7-hydroxy-1,2,3,4,6,7,8,8a-octahydro-pyrrolo[1,2-a]pyrazine as a clear oil.
