To a solution of 2-methoxymethoxy-4-methoxyphenyl boronic acid (2.89 g, 13.65 mmol) in MeOH (8-10 ml) and 6-benzyloxymethyl-5-iodo-4-propoxy-pyrimidine (5 g, 13 mmol) in toluene (75 ml) was added an aqueous solution of 2 M sodium carbonate (14 ml) followed by Tetrakis(triphenylphosphine)palladium (0) (1.25 g, 1.08 mmol). The reaction was allowed to stir at 90-95° for 18 h. The mixture was cooled to room temperature then diluted with ethyl acetate, washed with water, sat'd NH4Cl, 5% NaHCO3 solution, brine and dried (MgSO4). After removing the solvent, flash chromatography of the residue (silica gel, 1:1 t-butyl methyl ether/hexane) provided the title compound as a solid (3.41 g, 62%).
