Water → N-(4-iodophenyl)-N-methylpyrimidin-2-amine

Participants

Reaction Steps

Under an argon atmosphere, a solution of N-(4-iodophenyl)pyrimidin-2-amine (1.47 g) in anhydrous DMF (10 ml) was added dropwise to a suspension of sodium hydride (218 mg) in anhydrous DMF (8 ml), and the resulting mixture was stirred at room temperature for 75 minutes. Methyl iodide (0.37 ml) was added dropwise to the reaction solution and the resulting mixture was stirred at room temperature for another 1 hour. Water was added thereto and the resulting mixture was extracted with ethyl acetate. Organic layer was washed twice with water and once with saturated brine, and dried over anhydrous sodium sulfate. After removing anhydrous sodium sulfate by filtration, the filtrate was concentrated. The residue was recrystallized from hexane to obtain N-(4-iodophenyl)-N-methylpyrimidin-2-amine (1.38 g). NMR (H1, CDCl3): δ 3.49 (3H, s), 6.58 (1H, t, J=4.6 Hz), 7.07-7.09 (2H, m), 7.67-7.69 (2H, m), 8.32 (2H, d, J=4.6 Hz)
