反应条件: temp:80.01; pressure:0.00; stir:; See reaction.notes.procedure_details.

实验步骤: Under an argon atmosphere, a mixture of tripotassium phosphate (6.24 g) and water (15 ml) was added to a mixture of 2-chloro-5-methoxy-pyridine (2.05 g), 2-(diethylcarbamoyl)benzeneboronic acid (4.65 g), 1,1′-bis(diphenylphosphino)ferrocene-palladium(II) dichloride-dichloromethane complex (0.584 g) and toluene (30 ml), and the mixture was stirred at 80° C. for 2 hr. The reaction mixture was cooled to room temperature, water (20 ml), citric acid (2.2 g) and ethyl acetate were added and the mixture was stirred and filtered through celite. The filtrate was partitioned in a separatory funnel. The organic layer was washed with saturated brine, dried over anhydrous sodium sulfate, and filtered. The filtrate was concentrated under reduced pressure and the obtained residue was purified by silica gel column chromatography (eluent: n-hexane/ethyl acetate=1/1 to 1/2) to give a roughly purified product (1.144 g) of the title compound. This product was directly used for the next reaction without further purification. The reaction mixture was cooled to room temperature the mixture was stirred filtered through celite The filtrate was partitioned in a separatory funnel The organic layer was washed with saturated brine dried over anhydrous sodium sulfate filtered The filtrate was concentrated under reduced pressure the obtained residue was purified by silica gel column chromatography (eluent: n-hexane/ethyl acetate=1/1 to 1/2)
