Procedure

By using 2.0 g of 1-(2-benzimidazolyl)-1,3-butanedione and 2.5 g of 2-methylthio-1,3-dithiolylium perchlorate, the treatment was conducted in the same manner as in Example 1. The product was purified by silicagel chromatography, whereby 0.87 g (yield: 29%) of 2-(1,3-dithiol-2-ylidene)-1-(2-benzimidazolyl)-1,3-butanedione was obtained as crystals having a decomposition point of 254° C.
