Embodiment 1
[0042] 4-Bromophenylboronic acid (2.4g, 12mmol), potassium carbonate (3.32g, 24mmol) and palladium acetate (36mg, 0.16mmol) were added to 40mL of a mixed solvent of ethanol and water with a volume ratio of 3:1, and then 2 -Bromopyridine (790uL, 8mmol), react at 80°C for 2h. Cooled to room temperature, extracted with ethyl acetate and saturated brine, dried over anhydrous sodium sulfate, filtered and rotary evaporated, and passed through a silica gel column with a mixed solution of petroleum ether and ethyl acetate at a volume ratio of 100:1 to obtain 1.6 g of a white powder. Yield 86%. Add iridium trichloride (762.7mg, 2.54mmol) and white powder (1.5g, 6.44mmol) to 30mL of a mixed solvent of ethylene glycol monomethyl ether and water at a volume ratio of 3:1, and at 120°C Stir under reflux for 24h, after the reaction is completed, suction filter and wash the filter cake obtained by suction filtration with a small amount of water, ethanol and ether, and vacuum dry the filter c...
