Abstract

In the title compound, C21H24N2O3 [systematic name: methyl (20α)-16,17-dide-hydro-19α-methyl-18-oxayohimban-16-carb-oxy-l-ate], the mol-ecule adopts an L-type conformation. The crystal packing is governed by one N-H⋯π and one C-H⋯π inter-actions. The crystal cohesion is ensured by inter-molecular van der Waals contacts [shortest O⋯O contact = 3.199 (2) Å].
