Adding a certain compound to certain chemical reactions, such as: 1073-06-9, name is 1-Bromo-3-fluorobenzene, belongs to bromides-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 1073-06-9, Formula: C6H4BrF
Diacetoxypalladium (3.3 mg, 0.01 mmol) was added to a stirred mixture of methyl 2-morpholino-4-oxo-8-[(2R)-pyrrolidin-2-yl]chromene-6-carboxylate (121 mg, 0.34 mmol), (9,9-dimethyl-9H-xanthene-4,5-diyl)bis(diphenylphosphine) (16.61 mg, 0.03 mmol), 1-bromo-3-fluorobenzene (0.047 mL, 0.42 mmol) and cesium carbonate (165 mg, 0.51 mmol) suspended in 1,4-dioxane (3.3 mL). The resulting suspension was degassed with argon and then stirred at 100 C. for 20 h. The reaction mixture was allowed to cool to room temperature, and the crude product was purified by flash chromatography on silica gel eluting with 0 to 7% propanol in DCM. The solvent was evaporated to dryness to afford methyl 8-[(2R)-(1-(3-fluorophenyl)pyrrolidin-2-yl)]-2-morpholino-4-oxo-4H-chromene-6-carboxylate (120 mg, 79%) as a yellow oil which solidified on standing. Mass Spectrum: m/z [M+H]+=453.
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, 1-Bromo-3-fluorobenzene, other downstream synthetic routes, hurry up and to see.
