Synthetic Route of 866319-00-8 ,Some common heterocyclic compound, 866319-00-8, molecular formula is C7H5FN2, its traditional synthetic route has been very mature, but the traditional synthetic route has various shortcomings, such as complicated route, low yield, poor purity, etc., below Introduce a new synthetic route.
5-Fluoro-1H-pyrrolo[2,3-b]pyridine (1 g, 7.34 mmol) was dissolved in DMF (10 mL)Then, bromine (0.75 mL, 14.5 mmol) was added dropwise thereto, and the reaction was stirred at room temperature for 4 hours.Quenched with saturated aqueous sodium thiosulfate solution (100 mL)The reaction mixture was extracted with ethyl acetate (100 mL×2).The combined organic phases were washed with brine (100 mL×3)Filtered, concentrated under reduced pressure,The residue was subjected to silica gel column chromatography(PE/EtOAc (v/v) = 4/1) purified,The title compound was obtained as a yellow powder (0.6 g, 40%).
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. 866319-00-8, 5-Fluoro-1H-pyrrolo[2,3-b]pyridine, other downstream synthetic routes, hurry up and to see.
