Into the mixture were added 40 mL of tetrahydrofuran and 8 mL of water, and the mixture was degassed by being stirred under reduced pressure. Into the mixture were added 0.10 g (0.35 mmol) of tri-tert- butylphosphoniumtetrafluoroborate and 98 mg (0.11 mmol) of tris(dibenzylideneacetone)dipalladium(0), and the mixture was stirred under a nitrogen stream at 80 C for 14 hours. After the stirring, water was added to the mixture, followed by extraction of an aqueous layer with toluene. The obtained solution of the extract and an organic layer were combined and washed with water and brine, and an organic layer was dried with magnesium sulfate. The mixture was gravity filtered, and the filtrate was concentrated to give a solid. The solid was purified by silica gel column chromatography (toluene: ethyl acetate = 9:1) and recrystallized with methanol to give 1.4 g of a target white solid in a yield of 98 %.

85% | With [1,3-bis(2,6-diisopropylphenyl)imidazol-2-ylidene](3-chloropyridyl)palladium(ll) dichloride; potassium carbonate In methanol at 50℃; for 3h; | General procedure for Suzuki-Miyaura reaction General procedure: To a round bottle with a magnetic stir bar, catalyst, arylhydrazine (0.5 mmol), (hetero)arylboronic acid (0.75 mmol), Base (1.0 mmol) and 3 ml of solvent were added. The reaction mixture was conducted at 50 °C for the required time, and then the solvent was removed under reduced pressure. The residual was diluted with Et2O (5 mL), followed by extraction twice (2×5 mL) with Et2O. The organic layer was dried with anhydrous MgSO4, filtered and evaporated under vacuum. The conversions rates were analyzed by gas chromatography, based on the peak area normalization method. The corrected factor was determined by samples against a standard of n-heptane. The crude products were purified by silica-gel column chromatography using petroleum ether as an eluent, and the isolated yield was then calculated based on the feeding of the aryl halide. The isolated corresponding products were characterized by 1H NMR and 13C NMR. |
