실험 절차

A solution of 4-Iodo-2-fluorophenyl isocyanate (6-1, 5.15 g, 19.6 mmol) in Hexanes (80 ml) was treated with a solution of Methylamine (2M in THF, 9.8 mL, 19.6 mmol, 1.0 eq). A white precipitate formed as the mixture stirred at 23 deg C. for 30 min. The precipitate was collected via filtration and air dried, affording the title compound, N-(2-fluoro-4-iodophenyl)-N′-methylurea (6-2), as a white solid. 1H NMR (500 MHz, CDCl3) δ 7.89 (t, 2H, J=8.6 Hz), 7.47-7.38 (m, 2H), 6.31 (bs, 1H), 4.58 (bs, 1H), 2.88 (d, 3H, J-4.9 Hz). LRMS m/z: Calc'd for C8H8FIN2O (M+H) 295.1, found 294.9.
