Adding a certain compound to certain chemical reactions, such as: 143879-78-1, name is 3-Amino-2,6-difluorobenzonitrile, belongs to nitriles-buliding-blocks compound, can increase the reaction rate and produce products with better performance than those obtained under traditional synthetic methods. Here is a downstream synthesis route of the compound 143879-78-1, Computed Properties of C7H4F2N2
Example 4: 2,6-Difluoro-3-[5-(3-morpholin-4-ylphenoxy)-pyrimidin-2-ylamino]- benzonitrileA suspension of 4-[3-(2-chloro-pyrimidin-5-yloxy)phenyl]morpholine (180mg, 0.619 mmol), 3-amino-2,6-difluorobenzonitrile (95.3mg, 0.619mmol), ira(dibenzylidene- acetone)palladium(O) (28.3mg, 0.030mmol), 4,5-bis,(diphenylphosphino)-9,9- dimethyl-xanthene (35.8mg, 0.061mmol) and cesium carbonate (403mg, 1.238mmol) in degassed 1,4-dioxane (4mL) was heated at 80C for 2 days. The suspension was diluted with ethyl acetate and washed with water and brine. The organic phase was dried (MgS04) and the solvent removed under reduced pressure. The crude product was purified by column chromatography on silica (ethyl acetate:hexane, 1: 1) to afford 2,6-difluoro-3-[5-(3-morpholin-4-ylphenoxy)pyrimidin-2-ylamino]benzonitrile as a solid (l lOmg, 44%).Mass: (ES+) 410 (M+H)+ HPLC: 99.2%NMR: deltaEta ( 6-DMSO) 3.08 (4H, m), 3.69 (4H, m), 6.34 (IH, dd), 6.60 (IH, br s), 6.69 (IH, dd), 7.18 (IH, t), 7.40 (IH, t), 8.10 (IH, m), 8.35 (2H, s) and 9.59 (IH, s).
In the field of chemistry, the synthetic routes of compounds are constantly being developed and updated. I will also mention this compound in other articles, 3-Amino-2,6-difluorobenzonitrile, other downstream synthetic routes, hurry up and to see.
