At this point, we may carry out the reduction of the nitro compound to its amine derivative, the amine s de-azotization and the replacement of the azo group with a nitrile group by treatment with cuprous cyanide. We note that the reduction is specific for the nitro group, not altering the double bonds on the carboxyl group. Summarizing ...
