Related Products of 61150-58-1, A common heterocyclic compound, 61150-58-1, name is 2-(2-Bromo-4-fluorophenyl)acetonitrile, molecular formula is C8H5BrFN, 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.

To a solution of s2 in EtOH (10.0 mL) and H2O (5.0 mL) were successively added NaOH (2.94 g,73.5 mmol) and aqueous H2O2 (23 muL, 0.736 mmol) at room temperature. After the mixture washeated to reflux for 24 h, the reaction was quenched by addition of conc. HCl at 0 C. The crudemixture was extracted with EtOAc (x4) and the combined organic extracts were washed with brine,dried (Na2SO4), and concentrated in vacuo to give crude s3 (1.62 g) as pale yellow solid. Thiscrude material was used for next reaction without further purification.

The synthetic route of 61150-58-1 has been constantly updated, and we look forward to future research findings.
