Versuchsvorschrift

A mixture of 8-(nitromethyl)-1,4-dioxaspiro[4.5]decan-8-ol (16.0 g, 13.8 mmol) and 20% palladium hydroxide on carbon (3.2 g) in ethanol (160 mL) was hydrogenated at 50 psi (3.5×105 Pa) for 5 d on a Parr apparatus. The reaction mixture was filtered through CELITE filter agent and the filtrate was concentrated to give 8-(aminomethyl)-1,4-dioxaspiro[4.5]decan-8-ol as a clear oil (13.7 g, 99%) that solidified upon standing overnight.
