Participants

Reaction Steps

4-(4-Aminophenoxy)-6-cyano-7-methoxyquinoline (148 mg) was added to 5.5 ml of toluene, and the mixture was heated to reflux. After then adding phenyl isocyanate (0.08 ml), the mixture was further heated to reflux for 1 hour. After cooling, the precipitated solid was filtered out and washed with ethyl acetate/toluene=1/1 to obtain 150 mg of the title compound as light brown crystals. 1H-NMR Spectrum (DMSO-d6) δ (ppm): 4.05 (3H, s), 6.50-6.54 (1H, m), 6.96 (t, 1H, 7.2 Hz), 7.23 (2H, d, J=9.2 Hz), 7.27 (2H, d, J=7.2 Hz), 7.44 (2H, d, J=7.2 Hz), 7.56-7.62 (3H, m), 8.68-8.77 (3H, m), 8.83 (1H, brs).
