Reaction Steps

To an argon saturated solution of N-(4,6-dichloro-pyrimidin-2-yl)-methyl-amine (200 mg, 1.1 mmol), 5-chloro-2-ethoxy-phenylboronic acid (248 mg, 1.21 mmol) and palladium acetate (38 mg, 0.16 mmol) in dimethyl ethylene glycol (20 ml) was added a solution of sodium carbonate (240 mg, 2.2 mmol) in water (5 ml) followed by triphenylphosphine (66 mg, 0.33 mmol). After stirring at 70° C. under an argon atmosphere for 60 hours, the mixture was filtered through a pad of celite under suction and the filtrate was dried over magnesium sulfate. Evaporation of the solvent under reduced pressure provided [4-chloro-6-(5-chloro-2-ethoxy-phenyl)-pyrimidin-2-yl]-methyl-amine (300 mg, 90% yield).
