実験手順

A solution of 2-azaspiro[5.5]-undec-1-ene (15 g.; 0.10 mole) and one teaspoon (3 g.) of W2 Raney nickel catalyst in absolute ethanol (300 ml.) is hydrogenated at an initial pressure of 40 psi until hydrogen uptake ceases (2 hours). The mixture is filtered through celite and the filtrate concentrated under reduced pressure. Distillation of the residual liquid yields 88% of 2-azaspiro-[5.5]-undecane (13.5 g.), b.p. 55°-57° C./0.10 mm.
