Synthetic Route of 64248-64-2, These common heterocyclic compound, 64248-64-2, name is 2,5-Difluorobenzonitrile, 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.
General procedure: A mixture of benzonitrile 1 (10.0 mmol) and methylhydrazine (2.8 mL, 50.0 mmol) in EtOH (10.0 mL) was heated to reflux overnight. The mixture was cooled to rt and then concentrated. H2O (10.0 mL) and EtOAc (20.0 mL) were added to the residue. The organic layer was washed with H2O (10.0 mL), brine (10.0 mL), dried over Na2SO4, filtered, and concentrated in vacuo. The residue was subjected to silica-gel chromatography by using EtOAc/hexanes (1:1) as eluent to give the product 2.
Statistics shows that 2,5-Difluorobenzonitrile is playing an increasingly important role. we look forward to future research findings about 64248-64-2.
