To a solution of an optically-active compound of 6-(7H-pyrrolo[2,3-d]pyrimidin-4-yl)-1,6-diazaspiro[3.5]nonane-1-carboxylic acid benzyl ester (2.55 g) in methanol/tetrahydrofuran (51 ml/51 ml) was added 20% palladium carbon (510 mg), and the mixture was hydrogenated under 4 atmospheres for 5 hours. The mixture was filtered through Celite, and the filtrate was concentrated under reduced pressure. The resulting residue was slurry-washed with diisopropyl ether (30 ml) to give the titled compound (1.55 g).
