Crystal structure of methyl 3′-benzamido-4′-(4-meth­oxy­phen­yl)-1′-methyl­spiro­[indeno­[1,2-b]quinoxaline-11,2′-pyrrolidine]-3′-carboxyl­ate

In the title compound, C(35)H(30)N(4)O(3), the spiro C atom connects the five-membered pyrrolidine ring and the indeno­quinoxaline ring system. The pyrrolidine ring adopts a twist conformation. An intra­molecular N—H⋯N inter­action between the amino group and the pyrazine ring is observed. In the crystal, mol­ecules are linked by a pairs of C—H⋯O hydrogen bonds, forming inversion dimers.
