Reaction Steps
The process of Example 13 is followed except that the 2,3-dichloro-6-nitroquinoxaline is replaced by 1.5 g of 2,3-dichloro-6-nitro-7-methylquinoxaline and 1.5 g of the di(potassiomercapto)methylenemalononitrile is used. The recovered material is a dark yellow powder weighing 1.35 g with a calculated overall yield of 71 percent and has a melting point of 283° to 284° C.
