Procedure

Under an argon atmosphere, N-(4-iodophenyl)pyrimidin-2-amine (75 mg) was added to a suspension of sodium hydride (16 mg) in anhydrous DMF (3 ml), and the resulting mixture was stirred at room temperature for 30 minutes. The reaction solution was cooled to 0° C. and benzyl bromide (0.039 ml) was added thereto, followed by stirring the resulting mixture at room temperature for 1 hour. Saturated brine was added to the reaction solution and the resulting mixture was extracted 3 times with ethyl acetate. Organic layers were washed 3 times with water and dried 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:ethyl acetate/hexane=1/15) to obtain N-benzyl-N-(4-iodophenyl)pyrimidin-2-amine (67 mg).
