Procedure

4.52 g (10.0 mmol) of 3-(triphenylen-2-yl)phenyl trifluoromethanesulfonate, 3.0 g (13.0 mmol) of 4-dibenzothiopheneboronic acid, 0.46 g (0.5 mmol) of Pd2(dba)3, 0.82 g (2.0 mmol) of 2-dicyclohexylphosphino-2′,6′-dimethoxybiphenyl, 12.7 g (60.0 mmol) of K3PO4 and 150 mL of toluene and 15 mL of water were charged in a 250 mL round bottom flask. The reaction mixture was heated up to reflux under nitrogen for overnight. The reaction mixture was cooled and the organic extracts were purified by column chromatography and recrystallization. 4.3 g (88%) of white solid was obtained as product which was confirmed by proton NMR.
