2-Bromo-4′-chloro-1,1′-biphenyl Use and Manufacturing
To a solution of 1-bromo-2-iodobenzene (30 g, 106 mmol) and (4-chlorophenyl) boronic acid (16.9 g, 108.6 mmol) in dioxaneAfter the addition, a 2M potassium carbonate aqueous solution (100 ml) was added, and tetrakis triphenylphosphinopalladium (2.45 g, 2 molpercent) was addedAnd the mixture was heated and stirred for 4 hours. After the temperature was lowered to room temperature and the reaction was terminated, a potassium carbonate solutionAnd then layer separation was performed. After removal of the solvent, the product was subjected to column chromatography with hexane to obtain Compound A1, a white solid (25.3 g, 90percent)Sodium carbonate (19.8 g, 186.81 mmol) and tetrakis(triphenylphosphine)palladium(0) (1.05 g, 0.90 mmol) were added to a solution of 1, 2-dibromobenzene (12.8 ml, 105.98 mmol) and 4-chlorophenylboronic acid (14.1 g, 90.08 mmol) in toluene (170 ml) and water (80 ml). The mixture was purged with nitrogen and heated at reflux overnight. The reaction mixture was allowed to cool to room temperature, and partitioned between saturated aq. NH
