2-Chloro-4-fluoro-5-nitrobenzyl cyanide → 2-(5-Amino-2-chloro-4-fluorophenyl)acetonitrile

関与物質

反応手順

Hydrogen is injected at 25°-30° C., under normal pressure, into a mixture consisting of 8.9 g of 2-chloro-4-fluoro-5-nitrobenzyl cyanide, 1 g of Raney nickel in 90 ml of absolute ethanol, until the stoichiometric amount of hydrogen has been absorbed. After completion of the absorption of hydrogen, the reaction mixture is filtered and the alkaline filtrate is concentrated by evaporation. The residue consists of 7.5 g of 5-amino-2-chloro-4-fluorobenzyl cyanide having a melting point of 85°-86° C.
