Procedure
-
To a 100 mL 4-neck flask under nitrogen atmosphere, 2-([1,1'-biphenyl]-3-yl)-4-chloro-6-phenyl-1,3,5-triazine (1.10 g, 3.20 mmol), 4-(9H-carbazol-9-yl)phenylboronic acid pinacol ester (1.42 g, 3.85 mmol, 1.2 eq), potassium carbonate (0.89 g, 6.40 mmol), THF (20 mL), water (8 mL) and Organ’s catalyst (2.2 mg, 3.2 µmol, 0.1 mol%) were added, and the reaction mixture was refluxed for 1 hour. After confirming the disappearance of the raw material, the reaction mixture was cooled to room temperature, and then water (20 mL) was added and the precipitated solid was filtered out. The obtained crude product was filtered through a short pad of silica gel using CH2Cl2 as eluent and the filtrate was evaporated in vacuo to give a white solid. The solid was washed with methanol to give 1 (1.70 g, 96% yield) as a white powder.
