Abstract
A method for producing a heterocyclic nitrile in high yield by a gas-phase catalytic reaction of a heterocyclic carboxylic acid or an ester thereof with ammonia in the presence of a catalyst comprising an oxide of at least one element selected from copper and zinc, and an effective method for producing a heterocyclic aldehyde, using the heterocyclic nitrile thus obtained as a starting material, are provided.

A method for producing a heterocyclic aldehyde comprising a gas-phase catalytic reaction of a heterocyclic carboxylic acid or an ester thereof with ammonia in the presence of a catalyst comprising an oxide of at least one element selected from copper and zinc for producing a heterocyclic nitrile, and
- a catalytic hydrogenation of the heterocyclic nitrile thus produced in the presence of a hydrogenation catalyst and an acid in an aqueous solvent.
