To a solution of an optically-active compound of 6-benzyl-3-methyl-1,6-diazaspiro[3.4]octane-1-carboxylic acid tert-butyl ester (10.0 g) in tetrahydrofuran/methanol (50 ml/50 ml) was added 20% palladium hydroxide carbon (2.0 g), and the mixture was hydrogenated under 4 atmospheres for 24 hours. The mixture was filtered through Celite, and the filtrate was concentrated under reduced pressure to give the titled compound (7.3 g).
