Some common heterocyclic compound, 64248-62-0, name is 3,4-Difluorobenzonitrile, molecular formula is C7H3F2N, 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. Recommanded Product: 3,4-Difluorobenzonitrile
Pyrrole (2, 6, 6-trimethyltetrahydroindol-4-one) (1.0 g, 5.6 iranol) and 3, 4-difluorobenzonitrile (785 mg, 5.6 mmol) were dissolved in anhydrous DMF (20 mL) . To this NaH (95%, 270 mg, 11.2 mmol) was added and stirred at 50 0C for 30 min. The reaction mixture was cooled to RT and washed with H2O and EtOAc. The organic layer was dried over MgSO4. Column chromatography on silica eluting with EtOAc-hexanes (1:1) gave the product as a yellow solid (100% clean by LCMS, product M+H = 397.1) .
These compound has a wide range of applications. It is believed that with the continuous development of the source of the synthetic route 64248-62-0, its application will become more common.
