Synthetic Route of 115279-73-7, 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 115279-73-7 as follows.
To a solution of 4-hydroxy-3-methoxy-benzoic acid (90.0 mg; 0.54 mmol) in DCM (1.8 mL) were added few drops of DMF. Oxalyl chloride (180 uL; 2.12 mmol) was added dropwise to this solution, which then was stirred at room temperature for 16 hours. The solvent was evaporated under vacuum and the resulting yellow oil was dissolved in DCM (5.52 mL). This solution was added dropwise to a stirred mixture of l-(4-amino-phenyl)-cyclopentanecarbonitrile (100 mg; 0.54 mmol), prepared as in 3(B), and triethylamine (150 uL; 1.07 mmol) in DCM (4.6 mL). After stirring at room temperature for 3 hours, the solvent was evaporated under vacuum. The product was purified by preparative HPLC (Method Q), to yield the titled compound as a yellow oil (20.0 mg; 11% yield).1H NMR (300 MHz, CDC13) delta(ppm): 7.83 (br. s., 1 H), 7.64 (m, 2 H), 7.53 (d, 1 H), 7.43-7.50 (m, 2 H), 7.34 (dd, 1 H), 7.00 (d, 1 H), 3.99 (s, 3 H), 2.40-2.56 (m, 2 H), 1.84-2.17 (m, 6 H). LCMS (RT): 2.76 min (Method H); MS (ES+) gave m/z: 337.1 (MH+).
According to the analysis of related databases, 115279-73-7, the application of this compound in the production field has become more and more popular.
