What are the synthesis methods of 2-fluoro-6-methoxyphenylacetonitrile?
To prepare ethyl 2-hydroxy-6-methylaminobenzoate, the method is as follows:
First take an appropriate amount of 2-hydroxy-6-methylbenzoic acid, place it in a reactor, and dissolve it with an appropriate amount of organic solvent. This organic solvent, such as dichloromethane, chloroform, etc., can disperse the reactants uniformly, which is conducive to the reaction. Subsequently, slowly add thionyl chloride, and thionyl chloride reacts with the carboxyl group of 2-hydroxy-6-methylbenzoic acid. This process requires temperature control, usually between low temperature and room temperature, such as 0 ° C - 25 ° C, and stir evenly to make the reaction sufficient. After the reaction is complete, 2-hydroxy-6-methylbenzoyl chloride can be obtained, and this intermediate product has high activity.
The obtained 2-hydroxy-6-methylbenzoyl chloride is added dropwise to the reaction system containing ethanolamine at a suitable temperature, such as 20 ° C - 30 ° C. The amino group of ethanolamine reacts with the acid chloride group of benzoyl chloride to undergo nucleophilic substitution to generate 2-hydroxy-6-methylaminobenzamide. This step also needs to be fully stirred, and the reaction process should be paid attention to, which can be monitored by thin layer chromatography and other means.
Furthermore, 2-hydroxy-6-methylaminobenzamide is placed in a reaction vessel together with ethanol and concentrated sulfuric acid for esterification reaction. Concentrated sulfuric acid is used as a catalyst here, and the reaction temperature should be controlled at 60 ° C - 80 ° C, heated and refluxed for a certain period of time to esterify the carboxyl group of the amide and the hydroxyl group of ethanol to obtain the crude product of 2-hydroxy-6-methylaminobenzyl acetate.
Finally, the crude product is purified. First, it is washed with alkali solution to remove unreacted acid and other acidic impurities, and then extracted with an organic solvent to collect the organic phase. After drying with anhydrous sodium sulfate, filtration, and rotary evaporation to remove the solvent, a pure ethyl 2-hydroxy- 6-methylaminophenylacetate was obtained.
These methods, controlled by fine operation and conditions, can obtain the target product.
