Versuchsvorschrift

For instance, 4-hydroxypyridine is reacted with benzhydryl α-chloroacetate in a solvent such as N,N-dimethylformamide in the presence of potassium carbonate at a temperature of from 40° to 80° C. to form 1-benzhydryloxycarbonylmethyl-4-pyridone, followed by a reaction with phosphorus pentasulfide in a solvent such as tetrahydrofuran at a temperature of from 40° to 80° C. to obtain the product of the formula III.
