Reaction Steps
To a mixture of (E)-4-((1-methyl-1H-imidazol-2-yl)methyleneamino)isobenzofuran-1(3H)-one (590 mg, 2.4 mmol) and 4-fluorobenzaldehyde (300 mg, 2.4 mmol) in ethyl propionate (20 mL) was added a solution of sodium ethoxide in ethanol [sodium (220 mg, 9.6 mmol) in ethanol (10 mL)]. After the addition, the mixture was stirred at room temperature overnight. The mixture was quenched with water (10 mL) and solvent was removed in vacuum. The residue was dissolved in water, and then extracted with ethyl acetate (100 mL×4). The combined organic layers were washed with brine, dried over anhydrous sodium sulfate, and concentrated to give a crude product, which was purified by flash chromatography to give the title compound (100 mg, yield 10%). LC-MS (ESI) m/z: 410 (M+1)+.
