When making an a amide by hydrolysis of a nitrile in an aqueous medium containing a Raney copper catalyst, the yield of amide can be increased and the yield of impurities can be decreased by including vanadium metal in the catalyst. The vanadium may be present as Raney vanadium, often as an alloy in the Raney copper.
