YieldReaction ConditionsOperation in experiment
94% With potassium carbonate;bis-triphenylphosphine-palladium(II) chloride; In Solmix A-11; water; toluene; for 2h;Inert atmosphere; Reflux; First Step: 4-Bromoiodobenzene (1) (20.0 g), <strong>[212386-71-5]4-ethoxy-2,3-difluorophenylboronic acid</strong> (2)(14.4 g), potassium carbonate (29.3 g), Pd(Ph3P)2Cl2 (1.49 g), toluene (100 ml) , Solmix A-11 (100 ml), and water (100 ml) were put in a reaction vessel under a nitrogen atmosphere, and heated under reflux for 2 hours. The reaction mixture was cooled to 25 C, and then poured into water (500 ml) and toluene (500 ml), and mixed. The mixture was then allowed to stand until it had separated into two phases of organic and aqueous phases, and an extractive operation to an organic phase was carried out. The organic phase obtained was fractionated, washed with water, and then dried over anhydrous magnesium sulfate. The solution obtained was concentrated under reduced pressure, and the residue obtained was purified with a fractional operation by means of column chromatography using toluene as the eluent and silica gel as the stationary phase powder. The product was further purified by means of recrystallization from Solmix A-11 and dried, giving 20.8 g of 4-ethoxy-4'-bromo-2,3-difluoro-1,1'-biphenyl (3). The yield based on the compound (1) was 94.0%.
