Procedure

1.2 ml of N-methylpiperazine and 1.0 g of 2-methylthio-1,3-dithiolium perchlorate were treated in the same manner as in Example 26, and the product was recrystallized from acetone-ethyl ether, whereby 0.9 g (yield: 74.8%) of 1-(1,3-dithiol-2-ylidene)-4-methylpiperazinium perchlorate (Compound No. 31) was obtained as crystals having a melting point of 192° C.
