64248-58-4, A common compound: 64248-58-4, name is 1,2-Difluoro-4-iodobenzene, belongs to iodides-buliding-blocks compound, it can change the direction of chemical reaction, and react with certain compounds to generate new functional products. A new synthetic method of this compound is introduced below.
General procedure: Indole (1.0 mmol),Cs2CO3 (1.0 mmol), 2-bromopyridine (1.5 mmol), Cu2O (0.1 mmol), and DMA (3 mL) were added to a 5-mL vial. The vial was sealed with a crimp cap and placed in a Biotage initiator microwave cavity. After irradiation at 200C for the appropriate time and subsequent cooling, the reaction mixture was diluted with saturated aqueous ammonium chloride. Products were isolated by extraction into ethylacetate. The organic layer was dried over anhydrous magnesium sulfate, filtered, and concentrated. Products were purified by silica gel column chromatography using a hexane:ethyl acetate solvent. N-2-pyridylindole (2a) was obtained (80% yield) as yellow oil;
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, 1,2-Difluoro-4-iodobenzene, other downstream synthetic routes, hurry up and to see.
