YieldReaction ConditionsOperation in experiment
With sodium carbonate; triethylamine; palladium dichloride; ruphos; In tetrahydrofuran; water; for 18h;Inert atmosphere; Reflux; 11.0 g (103.8 mmol) of sodium carbonate are initially charged in 50 ml of water. 10.0 g (32.2 mmol) of <strong>[175278-30-5]4-bromo-2-ethyl-1-iodobenzene</strong>, 15.0 g (105.6 mmol) of 2-butoxy-[1,2]oxaborolane and 0.50 ml (3.67 mmol) of triethylamine are dissolved in 250 ml of tetrahydrofuran and added to the reaction solution and degassed under an argon stream for 40 min. Then 170 mg (0.96 mmol) of palladium(II) chloride (59percent Pd, anhydrous) and 0.90 g (1.92 mmol) of 2-dicyclohexylphosphino-2,6-diisopropoxy-1,1-biphenyl are added and the mixture is stirred under reflux for 18 h. On completion of conversion, the reaction mixture is cooled down to room temperature and admixed with water and methyl tert-butyl ether (MtBE), and the phases are separated. The aqueous phase is extracted with MtBE, and the combined organic phases are washed with saturated sodium chloride solution, dried over sodium sulphate, filtered and concentrated under reduced pressure. The crude product is filtered with dichloromethane/methanol through silica gel (300 g, 50 mum Combiflash system), and the product fractions are concentrated under reduced pressure. The desired product is obtained as a yellowish oil.
