ASISCHEM N42746 - Reference Information
| introduction | 3-ethoxy-4-methoxybenzaldehyde is slightly soluble in water and miscible in ethanol, ether, benzene and chloroform. it is a daily chemical essence and an organic intermediate in pharmaceutical chemistry. |
| Use | 3-ethoxy-4-methoxybenzaldehyde is an intermediate in the synthesis of flavors and drug molecules. In addition, in the synthesis and transformation, it mainly revolves around the benzene ring. The aldehyde group is a universal functional group conversion group, which can be easily converted into hydroxyl, cyano, carboxyl, and enamine and imine structures. |
| synthesis method | 3-ethoxy -4-hydroxybenzaldehyde (2 mmol), tetramethylammonium chloride (2.5 mmol), anhydrous cesium carbonate (2.5 mmol) and 1, 2-dimethoxyethane (2 mL) are added to the 10-mL microwave reaction container, and the reaction container is purged with argon before closing, the mixture in the microwave reactor was irradiated with magnetic stirring at 145°C for 60 minutes (microwave power limit set to 100 W), the container was discharged in a fume hood to remove trimethylamine, the reaction mixture was diluted with ethyl acetate (5 mL), the solids were filtered, the solids were washed with additional ethyl acetate (25 mL), and the filtrate was evaporated in vacuum. Using petroleum ether/ether as eluent, the residue was separated by column chromatography to obtain the target product 3-ethoxy-4-methoxybenzaldehyde.
