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 14869-41-1 as follows. 14869-41-1
2-Chlorethoxyacetic acid (1.11 g, 8 mmol) is dissolved in dichloromethane (22 mL), and thereto are added thionyl chloride (1.17 mL, 16 mmol) and dimethylformamide (30 muL, 0.4 mmol) successively at room temperature. After stirring at room temperature for 2.5 hours, the mixture is concentrated, and the residue is dissolved in dichloromethane (22 mL). To the mixture are added methyl 4-aminobenzoate (661 mg, 4 mmol) and pyridine (674 muL, 8 mmol) under ice-cooling, followed by stirring overnight. The reaction solution is washed with dilute hydrochloric acid, dried, and concentrated. The residue is subjected to silica gel column chromatography to give ethyl 4-(2-chloroethoxyacetylamino)benzoate (540 mg, 23.6percent).
According to the analysis of related databases, 14869-41-1, the application of this compound in the production field has become more and more popular.
