実験手順
(E)-N,N-Dimethyl-4-((1-oxo-1,3-dihydroisobenzofuran-4-ylimino)methyl)benzamide (924 mg, 3.0 mmol), 1-methyl-1H-imidazole-2-carbaldehyde (363 mg, 3.3 mmol), sodium (276 mg, 12 mmol) in ethanol (30 mL) and ethyl propionate (45 mL) were added and the mixture was stirred at room temperature overnight. Then the resulting mixture was evaporated under reduced pressure and extracted with ethyl acetate (100 mL×4) and concentrated. The crude product was purified by column chromatography (silica gel, petroleum ether/ethyl acetate=20:1 to 1:2) to afford the title compound as a yellow solid (500 mg, yield 37%). LC-MS (ESI) m/z: 447 (M+1)+.
