2-(1-Ethyl-5-meth-oxy-1H-indol-3-yl)-N-isopropyl-2-oxoacetamide.

In the title compound, C(16)H(20)N(2)O(3), the crystal packing is stabilized by weak π-π stacking inter-actions [centroid-centroid distances = 3.577 (9) and 3.693 (9) Å] and inter-molecular C-H⋯O and N-H⋯O hydrogen-bond inter-actions. The C atoms of the N-isopropyl group are disordered over two sets of sites with occupancies of 0.61(3) and 0.39(3).
