title: 5-Methyl-3,3-bis-(morpholin-4-yl)-1-[2-(morpholin-4-yl)eth-yl]-2,3-dihydro-1H-indol-2-one.
abstract: In the title compound, C(23)H(34)N(4)O(4), the morpholine rings adopt chair conformations. The N atom of the indol-2-one group is linked to the N atom of one morpholine ring through a flexible ethyl group with an almost cif conformation. In the crystal, molecules are linked by C-H⋯O interactions into infinite chains along the c direction. The almost parallel infinite chains are further inter-connected via other sets of C-H⋯O inter-actions, forming a three-dimensional framework.
