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 162705-07-9 as follows. HPLC of Formula: C18H21NO4
General procedure: A mixture of the appropriate piperidine (pyrroline) nitroxyl acids (0.5 mmol), compound 3 (0.5 mmol) and DMAP (20 mg) was stirred in anhydrous CH2Cl2 (20 mL) for 5 min at room temperature under nitrogen. DCC (106 mg, 0.5 mmol) was added and the mixture was stirred for 24 h. The reaction mixture was filtered and the filtrate was evaporated. The residue was subjected to column chromatography on silica gel with CH2Cl2-acetone to afford target compounds 14a-d, and their structures were confirmed from mp, IR, ESR and HRMS analyses.
According to the analysis of related databases, 162705-07-9, the application of this compound in the production field has become more and more popular.
