METHYL 3-HYDROXY-4-METHOXYBENZENECARBOXYLATE - Reference Information
| Application | methyl 3-hydroxy-4-methoxybenzoate is an important intermediate in organic synthesis of drugs, widely used in the pharmaceutical synthesis industry. |
| preparation | to a dry, three-necked flask were added 10.36G 3-hydroxy-4-methoxybenzoic acid methyl ester, 15.48G potassium carbonate, 9.15G of bromoethane and of acetone were heated to 50 ° C., reacted for 4.5 hours under magnetic stirring, and 9.15G of bromoethane was added after 2 hours of reaction. After completion of the reaction, the product was collected into a 250ml round-bottom flask, mixed with 80ml of saturated brine and 50ml of ethyl acetate, the filtrate was recovered, extracted with 50ml of ethyl acetate, and the organic phase was distilled under reduced pressure, methyl 3-ethoxy-4-methoxybenzoate is obtained as a solid product. |
