After the reaction was completed, distilled water and DCM (dichloromethane) were added at room temperature. The organic layer was dried with MgSO 4 and the solvent was removed by a rotary evaporator. The reaction product was purified by column chromatography (DCM: Hex = 1: 3) and recrystallized from methanol to obtain the desired compound 1-5-3 37 g (quant.).
98% With palladium diacetate; calcium acetate; In N,N-dimethyl-formamide; at 80℃;Inert atmosphere; 101g (410 mmol) of <strong>[50548-45-3]1-bromodibenzofuran</strong> was added to 500 ml flask under protectivegas, 273 g (1055 mmol) of bis (pinacolato) diborane (CAS 73183-34-3) wasdissolved in in 1500 ml dry DMF and degassed for 30 minutes. 121 g (1229 mmol) Calciumacetate and 8.4 g (37 mmol) palladium acetate are added subsequently, and thebatch was heated overnight at 80C . When the reaction was complete, themixture was diluted with 300 ml of toluene, and extracted with water. Thesolvent was removed in rotary evaporator, and the product was thenrecrystallized from heptane. Yield: 118 g (401mmol), 98% theory.
