To a solution of 3.03 g (23.39 mmol) of 6-chloropyrimidin-4-amine in 60 mL of dimethylformamide was added dropwise a solution of iodine monochloride (2.34 mL, 46.70 mmol) in 40 mL of dimethylformamide. Then the mixture was stirred at 45° C. overnight. The solvent was evaporated under reduced pressure and the residue was partitioned between dichloromethane and a 4% aqueous solution of sodium bicarbonate. The organic layer was washed with water and brine, dried over magnesium sulphate, filtered and the solvent was removed in vacuum. The product was purified by flash chromatography (0% to 20%, methanol-dichloromethane) to obtain 4.28 g (72% yield) of the title compound.
