Reaction Steps

To a solution of Aniline (205 mg, 2.2 mmol) and 2,4,5-Trichloropyrimidine (500 mg, 2.7 mmol) in 5 mL of Ethanol, was added 500 mg of Potassium carbonate. The reaction mixture was stirred at room temperature for 2 hours. Solvent was removed under reduced pressure. The residue was purified by silica gel flash chromatography with 10% Ethyl Acetate in Heptane to yield the desired product as an oil (370 mg, 70% yield).
