Under an argon atmosphere, 2-bromoethylmethyl ether (0.14 ml) and sodium hydride (48 mg) were added to a solution of N-(4-iodophenyl)pyrimidin-2-amine (300 mg) in anhydrous DMF (1 ml), and the resulting mixture was stirred at room temperature overnight. Saturated brine was added to the reaction solution and the resulting mixture was extracted with chloroform, followed by drying the organic layer over anhydrous sodium sulfate. After removing anhydrous sodium sulfate by filtration, the filtrate was concentrated. The residue was purified by column chromatography (silica gel, eluent: hexane/chloroform=1/10) to obtain N-(4-iodophenyl)-N-(2-methoxyethyl)pyrimidin-2-amine (233 mg).
