Cesium carbonate → HCID 58526509, compound

Participants

Reaction Steps

In a stream of argon, phenylboronic acid (904 mg), 4,6-bis(5-chlorobiphenyl-3-yl)-2-(3,5-dibromophenyl)-1,3,5-triazine (1.70 g), cesium carbonate (2.41 g) and tetrakis(triphenylphosphine)palladium (114 mg) were suspended in tetrahydrofuran (80 mL), and the mixture was refluxed for 18 hours. The reaction mixture was left to stand at room temperature, and then low-boiling ingredients were distilled away under a reduced pressure. Methanol was added to the reaction mixture, and the solid precipitate was recovered by filtration, and purified by silica gel chromatography using a chloroform/hexane (1:2 to 1:0) mixed liquid as a developing solvent to give 1.42 g of the target 2,4-bis(5-chlorobiphenyl-3-yl)-6-[(1,1′:3′,1″)-terphenyl-5′-yl]-1,3,5-triazine as a yellowish white powder (yield: 84%).
