How is (2,4-Dichlorophenyl)acetonitrile (CAS: 6306-60-1) typically synthesized?

(2,4-Dichlorophenyl)acetonitrile is synthesized by a multistep process starting from 2,4-dichlorophenylacetic acid, which is converted to the acetonitrile derivative using a series of reactions involving acetonitrile and a catalyst such as palladium(II) acetate. The synthesis typically involves nitration and subsequent deacylation steps, yielding a product with high selectivity and good yield.
