反应详情

The title compound was prepared by reacting 3-bromo-7-hydroxy-1-naphthonitrile (0.32 g, 1.28 mmol) with NCS (0.24 g, 1.8 mmol) in THF (25 mL) at 45° C. for 3 hr according to method C to yield 0.30 g (83%) of a yellow solid. An analytical sample was prepared by preparative reverse phase HPLC to yield the title compound as a white solid: mp 148-150° C.; 1H NMR (DMSO-d6): δ 7.47 (1H, d, J=8.98 Hz), 7.95 (1H, d, J=9.02 Hz), 8.32 (1H, d, J=2.08 Hz), 8.55 (1H, d, J=2.08 Hz), 11.33 (1H, s); MS (ESI) m/z280/282/284 (M−H)−
