Versuchsvorschrift
To a solution of 1,1-dimethylethyl 2-(3-hydroxy-1-{[(phenylmethyl)oxy]carbonyl}azetidin-3-yl)piperidine-1-carboxylate (595 mg, 1.52 mmol), prepared using procedures similar to those described in Reference 5, in methanol (5 mL) was added catalytic palladium on carbon (5% wt). The heterogeneous mixture was stirred under a hydrogen gas atmosphere for 15 hours at ambient pressure and then was filtered. The filtrate was concentrated in vacuo to afford 385 mg, 1.50 mmol (98%) of 1,1-dimethylethyl 2-(3-hydroxyazetidin-3-yl)piperidine-1-carboxylate as a colorless film without further purification.
