Abstract :
In the title compound, C35H30N4O3, the spiro C atom connects the fivemembered pyrrolidine ring and the indenoquinoxaline ring system. The pyrrolidine ring adopts a twist conformation. An intramolecular N—HN
interaction between the amino group and the pyrazine ring is observed. In the crystal, molecules are linked by a pairs of C—HO hydrogen bonds, forming inversion dimers.
