Reaction Steps
To a solution of 4,6-dichloropyrimidine (6.0 g, 0.04 mol) and 2-ethoxyphenylboronic acid (4.81 g, 0.029 mol) in mixture of dimethoxyethane (120 mL) and water (18 mL) were added NaHCO3 (6.72 g, 0.08 mol) and (PPh3)2PdCl2 (0.84 g) and the reaction mixture was allowed to reflux for 8 h, then it was concentrated under reduced pressure. The residue was dissolved in CH2Cl2 (100 mL), the resulting solution was washed with water (20 mL), dried over anhydrous K2CO3, filtered and the solvent removed under reduced pressure. The crude product was purified by flash chromatography on silica (eluent CH2Cl2) and recrystallized from hexanes. Yield of 4-chloro-6-(2-ethoxyphenyl)-pyrimidine 4.97 g (73%).
