The 1-benzhydryloxycarbonylmethyl-4-pyridothione represented by the formula V is produced in accordance with a method disclosed in J. Chem. Soc., p. 3610 (1958). For example, it is produced by reacting benzhydryl α-chloroacetate with 4-hydroxypyridine in a solvent of N,N-dimethylformamide in the presence of potassium carbonate at a temperature of from 40° to 80° C. to obtain 1-benzhydryloxycarbonylmethyl-4-pyridone, followed by reacting phosphorus pentasulfide with the compound thereby obtained in a solvent of tetrahydrofuran at a temperature of from 40° to 80° C.
