실험 절차

An optically-active compound of 3,3-difluoro-1,6-diaza-spiro[3.5]nonane-1-carboxylic acid benzyl ester 1 hydrochloride (11.2 g) was mixed with 4-chloro-7H-pyrrolo[2,3-d]pyrimidine (4.2 g), potassium carbonate (18.7 g) and water (104 ml), and the mixture was stirred for 16.5 hours with refluxing. The mixture was cooled to room temperature, and thereto were added ethyl acetate and water. The mixture was filtered, and the filtrate was separated and the resulting organic layer was washed with saturated aqueous sodium chloride solution, dried over anhydrous sodium sulfate and concentrated under reduced pressure. The resulting residue was purified by silica gel column chromatography (eluent: chloroform/acetone=3/1). The resulting residue was purified by silica gel column chromatography (eluent: chloroform/acetone=2/1) again to give the titled compound (12.0 g).
