366-99-4, 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 366-99-4 as follows.
To 124 (1.09 g, 3.5 mmol) dissolved in acetone (25 mL) was added 3-fluoro-p-anisidine (0.54 g, 3.5 mmol) in acetone (5 mL) followed by addition of 2.5 N NaOH (1.4 mL, 3.5 mmol) and water (3.5 mL). The reaction mixture was stirred and heated at reflux for 3 hours. The reaction mixture was extracted three times using dichloromethane; the combined organic layers were washed with brine and dried over potassium carbonate. The sample was filtered, concentrated in vacuo, and the resulting solid was dried overnight under vacuum to yield white solid (E15) (1.332 g, 97percent); mp 194¡ã C.; HPLC: Inertsil ODS 3V C18, 40:30:30 v:v:v [KH2PO4 (0.01 M, pH 3.2):CH3OH:CH3CN], 264 nm, Rt 33.2 min, 97.6percent purity; MS (TOF ES+) m/z 396 (35.0); 394 (M+H, 100).
According to the analysis of related databases, 366-99-4, the application of this compound in the production field has become more and more popular.
