実験手順: To a flask was added 2-benzyloxy-3-bromobenzonitrile (1.29 g, 4.47 mmol), 3-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)-8-azabicyclo[3.2.1]oct-2-ene-8-carboxylic acid tert-butyl ester (1.50 g, 4.47 mmol), and THF (30 mL), 2.0 M sodium carbonate in water (8.95 mL), and bis(triphenylphosphine)palladium(II) chloride (78 mg, 0.11 mmol). The reaction mixture was purged with nitrogen, heated to reflux overnight, cooled to room temperature, and concentrated. The resulting solution was diluted with DCM (25 mL) and washed with water (25 mL) The organic layer was collected, dried over anhydrous sodium sulfate, filtered, and concentrated. The crude product was purified by flash column chromatography eluting with ethyl acetate in hexanes (0-50%) to give partially purified product (1.2 g). (m/z): [M+H]+ calcd for C26H28N2O3 416.21; (-tert-butyl 361.2); found 361; (-Boc 317.2); found 317. The reaction mixture was purged with nitrogen heated to reflux overnight concentrated The resulting solution was diluted with DCM (25 mL) washed with water (25 mL) The organic layer was collected dried over anhydrous sodium sulfate filtered concentrated The crude product was purified by flash column chromatography eluting with ethyl acetate in hexanes (0-50%)

実験手順: To a flask containing sodium hydride (1.44 g, 60.0 mmol) suspended in DMF (60 mL, 800 mmol) at 0° C. was added benzyl alcohol (6.21 mL, 60.0 mmol) over 5 min. The reaction mixture was stirred at 0° C. for 30 min and then 3-bromo-2-fluorobenzonitrile (10.0 g, 50.0 mmol) in DMF (20 mL) was added. The reaction mixture was warmed to room temperature and stirred at 80° C. for 2 h, cooled to room temperature, and extracted with ethyl acetate (150 mL) and water (150 mL) The organic layer was washed with water (150 mL) and brine (150 mL), collected, dried over anhydrous sodium sulfate, filtered, and concentrated. The crude product was suspended with ethyl acetate:hexanes (1:3; 50 mL). The resulting suspension was stirred vigorously for 1 h, filtered, and dried. The mother liquor was concentrated and recrystallized. The crystals were combined and dried under vacuum to give the title compound (10.3 g). The reaction mixture was warmed to room temperature stirred at 80° C. for 2 h cooled to room temperature extracted with ethyl acetate (150 mL) and water (150 mL) The organic layer was washed with water (150 mL) and brine (150 mL) collected dried over anhydrous sodium sulfate filtered concentrated The resulting suspension was stirred vigorously for 1 h filtered dried The mother liquor was concentrated recrystallized dried under vacuum
