title: Methyl 3-[(1-butyl-1H-indol-3-yl)carbonyl-amino]propionate.
abstract: In the title mol-ecule, C(17)H(22)N(2)O(3), the mean plane of the terminal (C=O)OMe fragment and the indole plane form a dihedral angle of 78.94 (3)°. Inter-molecular N-H⋯O hydrogen bonds link the mol-ecules into chains extended along the c axis. The crystal packing exhibits π-π inter-actions, indicated by the short distance of 3.472 (2) Å between the centroids of the five-membered heterocycles of neighbouring mol-ecules.
