実験手順
The process of Example 13 is followed except that the 2,3-dichloro-6-nitroquinoxaline is replaced by 1.25 g of 2,3-dichloro-6,7-dinitroquinoxaline and 1.13 g of the di(potassiomercapto)methylenemalononitrile is used. The recovered material is a dark brown powder weighing 1.26 g with a calculated overall yield of 82 percent and has a melting point greater than 300° C.
