title: (Z)-3β-(2-Chloro-anilino)-17(20)-pregnene.
abstract: In the pregnene fragment of the title compound, C27H38ClN, the three six-membered rings exhibit chair conformations and the five-membered ring has a distorted envelope form with the fused C atom not bearing a methyl group as the flap atom. The amino group is involved in the formation of an intra-molecular N-H⋯Cl hydrogen bond. The crystal packing exhibits no short inter-molecular contacts.
