The process of Example 13 is followed except that the 2,3-dichloro-6-nitroquinoxaline is replaced by 0.75 g of 2,3-dichloro-6-methoxyquinoxaline and 0.90 g of the di(potassiomercapto)methylenemalononitrile is used. The recovered material is a dark yellow powder weighing 0.78 g with a calculated overall yield of 79 percent.
