A fluorinated benzonitrile building block
As a dihalogenated building block for the synthesis of APIs
5-Chloro-2-fluorobenzonitrile (CAS number 57381-34-7) is a building block derived from benzonitrile, with fluoride next to the cyano and chloride opposite to the fluoride function group. 5-Chloro-2-fluorobenzonitrile can be used in the synthesis of aminobenzo[b]thiophene, in cooperation with ethyl mercaptoacetate under basic conditions. The resulting product is used as a kinase inhibitor and has enormous potential for further derivatization to achieve tailored binding affinity.
5-Chloro-2-fluorobenzonitrile is also employed in the preparation of aryl ether inhibitors of Bacillus anthracis enoyl–ACP reductase.
