Application of 17247-58-4, 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 17247-58-4 as follows.
A stirred solution of the ketimime 1a’ (50 g, 187.1 mmol, available from Aldrich Chemical Company, Milwaukee, Wis.) under N2 in dry THF (400 mL) was cooled to -78 C. and treated with 1 M solution of K-tBuO (220 mL, 1.15 equiv.) in THF. The reaction mixture was warmed to 0 C. and stirred for 1 h and treated with bromomethylcyclobutane (28 mL, 249 mmol). The reaction mixture was stirred at room temperature for 48 h and concentrated in vacuo. The residue was dissolved in Et2O (300 mL) and treated with aq. HCl (2 M, 300 mL) The resulting solution was stirred at room temperature for 5 h and extracted with Et2O (1 L). The aqueous layer was made basic to pH 12-14 with aq. NaOH (50%) and extracted with CH2Cl2 (3×300 mL). The combined organic layers were dried (MgSO4), filtered, and concentrated to give pure amine (1b’, 18 g) as a colorless oil.
According to the analysis of related databases, 17247-58-4, the application of this compound in the production field has become more and more popular.
