実験手順

20 g of 4-methyl-4H-1,2,4-triazole-3-thiol and 19 g of potassium t-butoxide were added to a dimethylacetamide (130 ml) solution of 13 g of 6-chloro-3-[(4-hydroxyphenyl)thio]-N-(3-methyl-1,2,4-thiadiazol-5-yl)pyridine-2-carboxamide, and stirred under heat at 160° C. for 8 hours. At room temperature, chloroform and water were added to it, and its pH was controlled to 3 with aqueous 1 N hydrochloric acid solution added thereto. This was extracted with chloroform, and the organic layer was washed with saturated saline water, and dried with anhydrous magnesium sulfate. The solvent was evaporated away under reduced pressure, and the residue was purified through silica gel column chromatography (developing solvent: chloroform/methanol) to obtain 10.0 g of the entitled compound as a yellow solid.
