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 53250-82-1 as follows. 53250-82-1
General procedure: To a stirred solution of 11 (13.14 mmol) in 1,2-dichloroethane (240 mL) were added appropriate substituted anilines (19.71 mmol) and AcOH (13.14 mmol), and the mixture was heated to reflux for 2 h under nitrogen atmosphere. The reaction mixture was cooled to 0 C, and MeOH (60 mL) and THF (20 mL) were added. To it, (AcO)3BHNa (26.20 mmol) or NaBH4 (52.56 mmol) was added portionwise, and then the reaction mixture was allowed to warm to room temperature and stirred for an additional 3 h. The pH of the reaction mixture was adjusted to 7-8 at 0 C with 1 NHCl, and then the organic layer was separated. The aqueous layer was extracted with CH2Cl2 (2¡Á 300 mL). The combined organic layers was washed with brine (300 mL) and dried over anhydrous Na2SO4, filtered, and evaporated to dryness under reduced pressure. The residue was purified by MPLC on silica gel to afford the titled compounds as a solid.
According to the analysis of related databases, 53250-82-1, the application of this compound in the production field has become more and more popular.
