実験手順: To a solution of 2-fluoro-3-cyanopyridine (0.4 g, 3.27 mmol) in 30 mL tetrahydrofuran was added triethylamine (0.66 g, 6.5 mmol) and 3-aza-bicyclo[3.2.2]nonane (0.5 g, 3.9 mmol). The reaction was held at 50° C. for 12 hours, cooled and diluted with 100 mL ethyl acetate. The organics were washed with water (2×50 mL), brine (1×50 mL), dried (MgSO4) and concentrated. Column chromatography (20% ethyl acetate/hexanes) gave the title compound as a solid. MS (ESI/NH3) m/z 126 (M+H)+ cooled The organics were washed with water (2×50 mL), brine (1×50 mL) dried (MgSO4) concentrated

実験手順: To a solution of 3-azabicyclo[3.2.2]nonane (1.25 g) in dichioromethane (20 ml) and water (0.75 ml) was added dropwise a solution of bromoacetyl bromide (2.02 g) in dichloromethane (10 ml) at, 5°-10° C. The mixture was allowed to warm to room temperature and stirred for 1 hour at the same temperature. The reaction mixture was washed with a saturated sodium bicarbonate aqueous solution (10 ml) and a brine (10 ml). The organic layer was dried over magnesium sulfate. Filtration and evaporation gave N-bromomethylcarbonyl-3-azabicyclo[3.2.2]nonane (1.15 g). The compound was used in a following reaction step without further purification. The reaction mixture was washed with a saturated sodium bicarbonate aqueous solution (10 ml) The organic layer was dried over magnesium sulfate Filtration and evaporation

実験手順: 4-Acetoxy-2-naphthalenesulfonyl chloride (861 mg, 3.02 mmol) and 3-azabicyclo[3.2.2]nonane (379 mg, 3.02 mmol) were combined in CHCl3 (20 ml) and pyridine (20 ml) and the mixture was stirred at room temperature for 15 hr. At this time the solvent was evaporated under reduced pressure and the residue was partitioned between EtOAc and 1N aq HCl. The EtOAc was then washed with saturated aq NaHCO3, dried over Na2SO4, and concentrated. The residue was purified by flash chromatography using 1% acetone in CHCl3 to provide the pure product as a white foam (712 mg, 63% yield): 1H NMR (CDCl3) δ 1.52-1.84 (8H, m, 4×CH2), 2.02-2.13 (2H, br s, 2×CH), 2.46 (3H, s, CH3CO), 3.31 (4H, d, J=4.2 Hz, 2×CH2), 7.56-7.71 (3H, m, ArH), 7.92-8.02 (2H, m, ArH). At this time the solvent was evaporated under reduced pressure the residue was partitioned between EtOAc and 1N aq HCl The EtOAc was then washed with saturated aq NaHCO3 dried over Na2SO4 concentrated The residue was purified by flash chromatography
