Reference of 63069-50-1,Some common heterocyclic compound, 63069-50-1, name is 4-Amino-3-fluorobenzonitrile, molecular formula is C7H5FN2, 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.
1.13. Synthesis of 4-amino-3-chloro-5-fluoro-benzonitrile (mt. 21) j00260j A mixture of 4-amino-3-fluorobenzonitrile (184 mmol) and NCS (276 mmol) in AcOH (300 mL) was stirred at 70C for approximately 16 h. The mixture was concentrated. H20 was added to the residue and the solid product was filtered off and washed (sat. NaHCO3 and H20). To eliminate H20, THF was added and removed under reduced pressure to yield the desired product.
These compound has a wide range of applications. It is believed that with the continuous development of the source of the synthetic route 4-Amino-3-fluorobenzonitrile, its application will become more common.
