Reaction Steps
A batch with 2,4-dichloro-5-fluoropyrimidine (200 mg; 1.20 mmol; Aldrich Chemical Company Inc.), (4-fluoro-2-methoxyphenyl)boronic acid (224 mg; 1.31 mmol; Aldrich Chemical Company Inc.) and tetrakis(triphenylphosphin)palladium(0) (138 mg; 0.12 mmol) in 1,2-dimethoxyethane (3.6 mL) and 2 M solution of potassium carbonate (1.8 mL) was degassed using argon. The batch was stirred under argon for 16 hours at 90° C. After cooling the batch was diluted with ethyl acetate and washed with brine. The organic phase was filtered using a Whatman filter and concentrated. The residue was purified by column chromatography (hexane/ethyl acetate 1:1) to give the desired product (106 mg; 0.41 mmol).
