반응 단계
Condensation as shown in Step A of 5,6-diaminoindazole with a glyoxyloylthiophene in the presence of absolute alcohol results in ring formation of a mixture of 6-thienyl-1H-pyrazolo[3,4-g]quinoxaline and 7-thienyl-1H-pyrazolo[3,4-g]quinoxaline. These positional isomers can be separated by standard procedures, such as column chromatography.
