Abstract: In the title compound, C24H31NO2, ring B adopts a conformation between the boat and twisted-boat forms. This conformation best accommodates adverse intramolecular H...H interactions between the H atoms of the 7[beta]-substituent and the two nearest ring H atoms. The tilt angle between rings A and D is 28.6 (1).

Formula: C24H31NO2
