Reaktionsschritte

The process of Example 13 is followed except that the 2,3-dichloro-6-nitroquinoxaline is replaced by 3.0 g of 2,3-dichloro-6-methylquinoxaline and 3.84 g of the di(potassiomercapto)methylenemalononitrile is used. The recovered material is a yellow powder weighing 2.9 g with a calculated overall yield of 73 percent and has a melting point of 265° to 267° C.
