<p>A triazol-3-one derivative (1) or a salt thereof, which is useful as an antitumor agent, can be produced from a triazolyl sulfide derivative (2) in a single step as shown by the reaction formula by processing the triazolyl sulfide derivative (2), in an aprotic solvent, with one equivalent weight or more of water with respect to the triazolyl sulfide derivative (2) or a salt thereof and a base (3) of a higher equivalent weight than the equivalent weight of water.</p> |
