biostudies-literatureUnknown68(Pt 6)Lin HHIn the title compound, C(26)H(43)N(7)O, each piperazine ring adopts a chair conformation. Two 1-methyl-piperazine rings bond to one Csp(3) of the pyrrole ring via the piperazine N atoms, while the third one links to the N atom of the indolin-2-one unit through a flexible ethyl group with an almost syn conformation. In the crystal, mol-ecules are connected through methyl-ene-carbonyl C-H⋯O inter-actions into an infinite chain along the c axis. The almost parallel arrays are stacked, forming a three-dimensional framework.Acta crystallographica.
