Procedure

2,4-Dimethoxy-pyrimidine-5-boronic acid (1.16 g, 6.32 mmol) was dissolved in degassed n-PrOH (22 ml) and then 2-fluoro-6-methyl-3-iodopyridine (870 mg, 3.67 mmol), Na2CO3 (778 mg, 7.34 mmol), PPh3 (96 mg, 0.37 mmol) and Pd(OAc)2 (41 mg added in three portions) were added. The suspension was stirred at reflux for 2.5 hours. The solvent was evaporated under vacuum and the crude was partitioned between water and DCM. The organic phase was dried (Na2SO4) and evaporated. The crude was triturated with iPrOH to give 691 mg of the title compound (75% yield).
