Reference of 957207-58-8, 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 957207-58-8 as follows.
To a 100 mL round-bottomed flask was added methyl 4-bromo-2-(trifluoromethyl)benzoate (2.25 g, 8.00 mmol), fluorovinyl) (methyl)diphenylsilane (3.58 g, 14.8 mmol), and 1,3-dimethylimidazolidin-2-one (40 mL). Tetrakis(triphenylphosphine)palladium(0) (0.459 g, 0.400 mmol), copper(I) iodide (0.0760 mg, 0.400 mmol), and cesium fluoride (3.62 g, 23.9 mmol) were added and the reaction was stirred at room temperature for 24 hours under a nitrogen atmosphere. Water was added to the mixture and the mixture was diluted with 3:1 hexanes/diethyl ether. The layer was separated, and the organic layer was dried over sodium sulfate, concentrated, and the residue was purified by flash column chromatography provided the title compound as a colorless oil (2.00 g, 96percent): 1H NMR (400 MHz, CDCl3) delta 7.96-7.87 (m, 1H), 7.83 (dq, J=8.1, 0.7 Hz, 1H), 7.77 (dd, J=8.2, 1.7 Hz, 1H), 5.23 (dd, J=48.6, 4.0 Hz, 1H), 5.07 (dd, J=17.4, 4.0 Hz, 1H), 3.95 (s, 3H); 19F NMR (376 MHz, CDCl3) delta?59.92, ?108.73 (d, J=1.4 Hz); EIMS m/z 248 ([M]+)
