Versuchsvorschrift
5-(Phenylmethyl)-5-azaspiro[2.4]heptan-7-ol (assumed 941.9 mg, 4.63 mmol) was dissolved in a solution of 4.6 mL of 1N aq HCl in 40 mL of MeOH, degassed and placed under argon. 10% Pd/C (280 mg) was added, and the contents were thoroughly degassed and placed under a hydrogen balloon overnight. The contents were then degassed and filtered through Celite, and the Celite pad was washed with MeOH. The resulting filtrate was concentrated in vacuo and azeotroped with MeOH (3×40 mL) to provide the pure 5-azaspiro[2.4]heptan-7-ol hydrochloride (685 mg, 99%). LCMS: (M+H)+: not detected.
