Reaction Conditions:
with tris-(dibenzylideneacetone)dipalladium(0);tri-tert-butyl phosphine;sodium tertiary butoxide in toluene; for 24 h;Reflux;
Steps:
8 8. Synthesis of Compound H8
To a round bottom flask was added 2-bromodibenzothiophene (1.00 g, 3.8 mmol),aminobiphenyl (0.71 g, 4.18 mmol),sodium tert-butoxide (0.51 g, 5.32 mmol),tris (dibenzylideneacetone) dipalladium (0) (0.104 g, 0.114 mmol) was dissolved in 50 ml of toluene. tri-tert-butylphosphine (0.228 g, 0.46 mmol) was added thereto, and the mixture was stirred under reflux for 24 hours.After confirming with HPLC and LC-MASS, the reaction was terminated. After removal of the solvent, it was extracted with MC / H2O. column (EA: Hex = 1: 4) and reprecipitated with MC / hexane. Vacuum drying and sublimation purification were conducted to obtain a solid compound (1.05 g, yield = 80%).
