Reaction Conditions:
with aluminum (III) chloride;sodium iodide in acetonitrile at 80; for 18 h;
Steps:
2
Add acetonitrile (40ml) to a 100ml eggplant bottle,Aluminum trichloride (0.752g, 5.64mmol, 1.1eq),NaI (2.305 g, 15.38 mmol, 3.0 eq) and o-vanillin (0.780 g, 5.13 mmol),Heat to 80 ° C, stop stirring after 18 hours of reaction.After cooling to room temperature, it was acidified with 2 mol/L of dilute hydrochloric acid (10 ml), and extracted with ethyl acetate (50 ml × 3). The organic phase was combined and washed with saturated aqueous sodium thiosulfate (10 ml). Washed with saturated brine (10 ml), dried over anhydrous magnesium sulfate, filtered, evaporated, evaporated, evaporated. )purification,0.620 g of 2,3-dimethoxybenzaldehyde were obtained (yellow solid, yield 87%).
