Application of 14062-24-9, In the chemical reaction process, reaction time, type of solvent, can easily affect the result of the reaction, thereby determining the yield and properties of the reaction product. An updated downstream synthesis route of 14062-24-9 as follows.

Ethyl trifluoroacetate (3.57 g, 25.2 mmol) and sodium (580 mg, 25.2 mmol) were added to a solution of ethyl 2-(4-chlorophenyl)acetate (5.0 g, 25.2 mmol) in ether (8 mL), followed by heating to reflux for 24 hours. After the reaction was completed, 2N hydrochloric acid (50 mL) was added thereto, and the resultant product was extracted with ether (20 mL*3). The mixed organic layer was washed with water (20 mL*3), and dried over anhydrous magnesium sulfate, and the solvent was concentrated under reduced pressure. The obtained residue was purified by silica gel column chromatography (hexane:ethyl acetate=4:1), whereby ethyl 2-(4-chlorophenyl)-4,4,4-trifluoro-3-oxobutanoate (2.42 g, yield: 34%) was obtained as a yellow solid.

According to the analysis of related databases, 14062-24-9, the application of this compound in the production field has become more and more popular.
