To a solution of an optically-active compound of 3-methyl-6-(7H-pyrrolo[2,3-d]pyrimidin-4-yl)-1,6-diazaspiro[3.5]nonane-1-carboxylic acid benzyl ester (2.84 g) in methanol/tetrahydrofuran (14 ml/14 ml) was added 10% palladium carbon (568 mg), and the mixture was hydrogenated under 4 atmospheres. The mixture was filtered through Celite, and the filtrate was concentrated under reduced pressure. The resulting residue was slurry-washed with toluene/tetrahydrofuran (95/5, 9 ml) to give the titled compound (1.74 g).
