Procedure
In DMF was dissolved 2.00 g of the (E)-4-[2-[2-[[(p-methoxyphenyl)sulfonyl]amino]phenyl]ethenyl]pyridine obtained in Example 3, followed by addition of 1.91 g of sodium methanethiolate, and the mixture was stirred at 100° C. overnight and then after-treated. The resulting crystals were recrystallized from methanol to provide 0.19 g of the title compound (white powders).
