実験手順: An oven dried resealable Schlenk tube was evacuated and backfilled with argon and charged with palladium acetate (2.2 mg, 0.01 mmol, 1.0 mol %), 2-(di-tert-butylphosphino)biphenyl (6.0 mg, 0.020 mmol, 2.0 mol %), phenylboron dihydroxide (183 mg. 1.5 mmol), and potassium fluoride (174 mg, 3.0 mmol). The tube was evacuated and backfilled with argon, and THF (1 mL) and 2-chlorobenzyl cyanide (152 mg, 1.0 mmol) were added through a rubber septum. The tube was sealed with a teflon screwcap, and the reaction mixture was stirred at room temperature until the starting aryl chloride had been completely consumed as judged by GC analysis. The reaction mixture was then diluted with ether (30 mL) and poured into a separatory funnel. The mixture was washed with 1.0 M NaOH (20 mL), and the aqueous layer was extracted with ether (20 mL). The combined organic layers were washed with brine (20 mL), dried over anhydrous magnesium sulfate, filtered, and concentrated. The crude material was purified by flash chromatography on silica gel to afford 178 mg (92%) of the title compound.

実験手順: To a solution of 2-chloro-phenyl-acetonitrile (15.0 g, 99.0 mmol) in the dichloromethane (50 mL) and H2SO4 (40 mL) is slowly added a mixture of H2SO4 (14 mL) and HNO3 (5.5 mL) at 0° C. The reaction mixture is stirred at 0° C. for 20 minutes, warmed to room temperature for 30 minutes and then concentrated to remove organic solvent. The solution is poured into a beaker containing ice-water (400 mL) to give a crystalline precipitate, which is collected by vacuum filtration and washed with water to give the title intermediate (13.4 g, 69.0%). warmed to room temperature for 30 minutes concentrated to remove organic solvent The solution is poured into a beaker containing ice-water (400 mL) to give a crystalline precipitate, which is collected by vacuum filtration washed with water

実験手順: Sodium hydride (60% dispersion in mineral oil, 1.28 g, 45 mmol) was suspended in DMF (20 mL) and cooled in an ice bath under a nitrogen atmosphere. (2-Chloro-phenyl)-acetonitrile (1.77 g, 11.7 mmol) in DMF (5 mL) was added slowly, and the mixture stirred for 2 hours. Bis-(2-chloro-ethyl)-carbamic acid tert-butyl ester (3.3 g, 11.1 mmol) in DMF (5 mL) was then added and the mixture heated to 75° C. for 6 hours. The solvent was removed by evaporation under vacuum and the residue dissolved in ethyl acetate (50 mL), washed with water, then brine, dried over magnesium sulphate, filtered and the solvent removed by evaporation under vacuum. The residue was purified by silica chromatography eluting with a mixture of ethyl acetate and hexane. The fractions containing the desired products were combined and the solvent removed by evaporation to give the title compound as an orange gum (1.1 g). LCMS m/z 321.0 [M+H]+. R.T.=4.76 min (Analytical Method 4). cooled in an ice bath under a nitrogen atmosphere The solvent was removed by evaporation under vacuum the residue dissolved in ethyl acetate (50 mL) washed with water brine, dried over magnesium sulphate filtered the solvent removed by evaporation under vacuum The residue was purified by silica chromatography eluting with a mixture of ethyl acetate and hexane The fractions containing the desired products the solvent removed by evaporation

実験手順: 4-Bromoaniline (6.4 g, 37 mmol) was placed into a three-neck reactor, and the reactor was flushed with argon for 20 min. 60 mL anhydrous toluene was added. After cooling to 0° C., trimethylaluminum (28 mL, 2.0M solution in toluene, 56 mmol) was added slowly to keep the inner temperature below 20° C. Over 0.5 h, the addition was completed. Ice bath was removed, and the reaction mixture was warmed to room temperature and then stirred for additional 2.5 hrs. A solution of 2-chlorobenzyl cyanide (8.4 g, 55 mmol) in 35 mL anhydrous toluene was added, and the reaction mixture was heated to 80° C. After 18 hrs, the reaction mixture was cooled to room temperature and poured over a slurry of silica gel in CHCl3/MeOH (4/1, 400 mL). After stirring for 30 min, the mixture was filtered and the residue was washed with a mixture of CHCl3/MeOH (4/1). The combined filtrates were concentrated in vacuo, and the resulting solid was washed with hexane to give a light pink solid (5.78 g, 48% yield). the reactor was flushed with argon for 20 min 60 mL anhydrous toluene was added the inner temperature below 20° C the addition Ice bath was removed the reaction mixture was warmed to room temperature the reaction mixture was heated to 80° C After 18 hrs the reaction mixture was cooled to room temperature After stirring for 30 min the mixture was filtered the residue was washed with a mixture of CHCl3/MeOH (4/1) The combined filtrates were concentrated in vacuo the resulting solid was washed with hexane
