実験手順

Under an argon atmosphere, a solution of N-(4-iodophenyl)pyrimidin-2-amine (68 mg) in anhydrous DMF (1.0 ml) was added dropwise to a solution of sodium hydride (16 mg) in anhydrous DMF (1.0 ml), and the resulting mixture was stirred at room temperature for 30 minutes. To the reaction solution, a solution of 4-acetoxybenzyl chloride (0.04 ml) in anhydrous DMF (0.5 ml) was added, 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. Organic layer was 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: hexane/ethyl acetate=6/1) to obtain (4-acetoxybenzyl)-(4-iodophenyl)pyrimidin-2-ylamine (67 mg). NMR (HL, CDCl3): δ 2.28 (3H, s), 5.22 (2H, s), 6.63 (1H, t, J=4.6 Hz), 6.98-7.02 (4H, m), 7.26 (2H, d, J=8.1 Hz), 7.64-7.67 (2H, m), 8.34 (2H, d, J=4.6 Hz)
