%X In the title compound, C26H43N7O, each piperazine ring adopts a chair conformation. Two 1-methylpiperazine rings bond to one Csp3 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, molecules are connected through methylene¨Ccarbonyl C¡ªH...O interactions into an infinite chain along the c axis. The almost parallel arrays are stacked, forming a three-dimensional framework.
