Take an appropriate amount of 2-phenylquinoline-4-carboxylic acid and place it in the reaction vessel, add an appropriate amount of chlorination reagent, such as thionyl chloride ($SOCl_2 $), and add a few drops of N, N-dimethylformamide (DMF) as the catalyst. 2-Phenylquinoline-4-formyl chloride can be obtained after the reaction is completed and the excess chlorination reagent is removed at a suitable temperature, such as heating and refluxing.
Subsequently, 2-oxo-2-phenylethanol is reacted with the above acid chloride. Dissolve 2-oxo-2-phenylethanol with an appropriate amount of acid binding agent, such as triethylamine, in a suitable organic solvent, such as dichloromethane. Under low temperature, such as ice bath conditions, slowly add the solution of 2-phenylquinoline-4-formyl chloride dropwise. After the reaction is completed, bring it to room temperature and continue the reaction for a period of time. After the reaction is completed, the product is purified by means of washing with water, drying, column chromatography, etc., to obtain 2-oxo-2-phenethyl 2-phenylquinoline-4-carboxylic acid ester.
Second, the ester exchange method is adopted. Using 2-phenylquinoline-4-carboxylic acid methyl ester and 2-oxo-2-phenylethanol as raw materials, an appropriate amount of ester exchange catalyst is added, such as p-toluenesulfonic acid or organotin catalyst. In a suitable solvent, such as toluene, heat to reflux. During the reaction, the generated methanol is continuously removed to push the reaction in the positive direction. After the reaction reaches the desired level, the target product is obtained through cooling, washing, separation, purification and other steps.
Or, react with 2-phenylquinoline-4-carboxylate with 2-oxo-2-phenethyl halide. First prepare 2-phenylquinoline-4-carboxylate, and react 2-phenylquinoline-4-carboxylic acid with an appropriate amount of base, such as potassium carbonate, to form the corresponding carboxylate. After that, the carboxylate is heated with a 2-oxo-2-phenethyl halide, such as 2-oxo-2-phenethyl bromide, in a suitable organic solvent, such as N, N-dimethylformamide (DMF). After the reaction is completed, after post-treatment, such as extraction, washing, drying, recrystallization, etc., a pure 2-oxo-2-phenethyl-2-phenylquinoline-4-carboxylic acid ester is obtained.
