실험 절차
A solution of 9.50 g (0.030 mole) 2-benzyl-7-ethyl-2,7-diazaspiro[4.4]nonane dihydrochloride in 100 ml methanol was hydrogenated with 1.0 g 20% palladium on carbon catalyst at 4.5×105Pa for 22 hours. After filtration, the solution was concentrated to a syrup and crystallized from acetonitrile to afford 6.66 g of the title compound, mp 168°-172° C.
