Versuchsvorschrift

Add 10% Pd/C (0.079 g; 37.12 μmoles) to 4-(N-Hydroxycarbamimidoyl)-piperidine-1-carboxylic acid tert-butyl ester (805 mg; 1.00 equiv; 3.31 mmoles) in acetic acid (15 mL; 261.77 mmoles) and acetic acid anhydride (0.5 mL; 5.29 mmoles). Hydrogenate at room temperature for 7 hr at 20 PSI. Purge flask with nitrogen to provide 1.2 g of a foam. Triturate with acetonitrile and filter to provide 270 mg (28%) of the product as a white solid.
