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. 366-99-4
To a mixture of cyanuric chloride (0.368 g, 2 mmol) in CH3CN at approximately -10 to -20 C. was added 3-fluoro-p-anisidine (0.28 g, 2 mmol) in CH3CN followed by the addition of N,N-diisopropylethylamine (DIEA) (0.35 mL, 2 mmol) and stirred for an hour. The reaction mixture was then allowed to reach room temperature for an hour. The second step was continued without further purification. Cycloheptylamine (0.25 mL, 2 mmol) and DIEA (0.35 mL, 2 mmol) were added and the reaction mixture was stirred overnight at rt. The third step was also preceded without any further purification. S-(-)-2-aminomethyl-N-ethyl pyrrolidine (0.29 mL, 2 mmol) and DIEA (0.35 mL, 2 mmol) were added and the reaction mixture was refluxed overnight. The reaction mixture was diluted with ethyl acetate and washed with brine. The organic layer was separated and dried over potassium carbonate, filtered, and concentrated under reduced pressure affording 0.920 g crude material. The crude material was purified by column chromatography to yield a white solid 139 (0.550 g, 60%), mp 75-77 C.; HPLC: Inertsil ODS-3V C18, 40:30:30 [KH2PO4 (0.01M, pH 3.2): CH3OH: CH3CN], 264 nm, Rt 7.9 min, 95.9% purity; MS (ESI): m/z 458 (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.
