実験手順
4-amino-6-fluoroisobenzofuran-1(3H)-one (1.5 g, 8.98 mmol), 4-fluorobenzaldehyde (1.67 g, 13.47 mmol) and 12.75 g of MgSO4 were added into 40 ml of DCM and stirred under reflux overnight, then the mixture was evaporated under reduced pressure and the residues was dried in vacuum. 850 mg of (E)-6-fluoro-4-(4-fluorobenzylideneamino)isobenzofuran-1(3H)-one was obtained. 1H-NMR (400 MHz, CDCl3) δ (ppm): 5.37 (s, 2); 7.09-7.12 (dd, 1H), 7.19-7.23 (t, 2H), 7.43-7.45 (dd, 1H), 7.92-7.95 (m, 2H), 8.49 (s, 1H); LC-MS (ESI) m/z: 274 (M+1)+.
