Synthetic Route of 36282-26-5,Some common heterocyclic compound, 36282-26-5, name is 2-Bromo-4-fluorobenzonitrile, molecular formula is C7H3BrFN, 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.
Pyrrole (2, 6, 6-trimethyltetrahydroindol-4-one) (1.5 g, 8.5 mmol) and 2-bromo-4-fluorobenzonitrile (1.69 g, 8.5 mmol) were dissolved in anhydrous DMF (50 mL) . To this NaH (95%, 408 mg, 17.0 mmol) was added and stirred at 50 0C for 1 h. The reaction mixture was cooled to RT and H2O was added. Product crashed out of solution and was filtered and dried under vacuo (2.4 g, 79%). (100% clean by LCMS, product M+H = 357).
These compound has a wide range of applications. It is believed that with the continuous development of the source of the synthetic route 2-Bromo-4-fluorobenzonitrile, its application will become more common.
