実験手順: To an ice cooled solution of 3.69 g of 4-amino-3,3-dimethyl-1-[1-(R)-phenylethyl]-pyrrolidine in 40 ml of anhydrous tetrahydrofuran there was added 4.92 g of 2-(tert-butoxycarbonylamino)-2-phenylacetonitrile and the mixture was stirred at room temperature for 1 hr. Solvent was removed under reduced pressure, and to the residue there was added ethyl acetate. The mixture was washed with a 1N sodium hydroxide aqueous solution three times and then dried. Solvent was then removed under reduced pressure. The residue was purified through column chromatography using 200 g of silica gel in a column with chloroform as the eluant containing from 1% to 5% methanol to yield 4.32 g of the titled compound. Solvent was removed under reduced pressure to the residue there was added ethyl acetate The mixture was washed with a 1N sodium hydroxide aqueous solution three times dried Solvent was then removed under reduced pressure The residue was purified through column chromatography containing from 1% to 5% methanol

実験手順: To an ice-cooled solution of 2.9 g of 8-amino-6-[1-(R)-phenylethyl]-6-azaspiro[3.4]octane in 30 ml of tetrahydrofuran there was added 3.3 g of 2-(tert-butoxycarbonyl-amino)-2-phenylacetonitrile and the resulting mixture was stirred at room temperature for 30 min. The solvent was removed under reduced pressure, and ethyl acetate was added to the resulting residue. The mixture was washed with a 1N sodium hydroxide aqueous solution three times and then dried. The solvent was removed under reduced pressure and the resulting residue was purified by column chromatography using 50 g of silica gel. The column was eluted with chloroform, chloroform containing methanol and 4.1 g of the titled compound was obtained from a eluate when the eluant was chloroform containing 1% (v/v) of methanol. The solvent was removed under reduced pressure, and ethyl acetate was added to the resulting residue The mixture was washed with a 1N sodium hydroxide aqueous solution three times dried The solvent was removed under reduced pressure the resulting residue was purified by column chromatography The column was eluted with chloroform, chloroform containing methanol
