Reaktionsschritte

2,4-Dimethoxy-pyrimidine-5-boronic acid (966 mg, 5.3 mmol) was dissolved in degassed n-PrOH (60 ml) and then 2-bromo-6-fluoropyridine (850 mg, 4.8 mmol), Na2CO3 (1.676 g, 15.8 mmol), PPh3 (400 mg, 1.52 mmol) and Pd(OAc)2 (116 mg) were added. The suspension was stirred at reflux for 3 hours. The solvent was evaporated under vacuum and the crude was partitioned between water and ethyl acetate. The organic phase was dried (Na2SO4) and evaporated. The crude was triturated with iPrOH to give 650 mg of the title compound as a white powder (52% yield).
