The title compound, C22H29NO, is built up from five fused
rings, four of which are six-membered and one five-membered. The ring adjacent to the five-membered ring adopts a chair conformation.
Comment
Testosterone derivatives have a high biological activity and have been widely used in the preparation of hormone-based drugs (Alvarez-Ginarteet al., 2005). As part of our continuing interest in the structure–activity relationship of testosterone derivatives, we have isolated the product, (I), from the reac-tion of propargylamine and 17-hydroxy-10,13-dimethyl-1,7,8,10,11,12,13,15,16,17-decahydro-2H-cyclopenta[a ]phen-anthren-3(4H,9H,14H)-one.
The molecular structure of (I) is illustrated in Fig. 1. It is built up from five fused rings, four of which are six-membered and one five-membered. The C4/C5/C17–C20 ring fused with the five-membered ring adopts a chair conformation (Cremer & Pople, 1975). The other rings have no obvious conforma-tions. There is an O—H N hydrogen-bond interaction, building a zigzag chain parallel to the a axis (Table 1 and Fig. 2).
Experimental
The title compound was prepared according to the procedure of Yan
et al. (2006). Crystals were obtained by slow evaporation of a methanol solution at room temperature.

H atoms were included in calculated positions and refined using a riding model, withUiso(H) = 1.2 (or 1.5 for methyl H atoms) times
Ueq(C). C—H distances were constrained to 0.96 A˚ for methyl H atoms, 0.97 A˚ for methylene H atoms, 0.98 A˚ for methine H atoms, and 0.93 A˚ for the remainder, and O—H = 0.82 A˚. In the absence of significant anomalous scattering, Friedel pairs were averaged, and the absolute configuration assigned arbitrarily.

Special details
Geometry. All e.s.d.'s (except the e.s.d. in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell e.s.d.'s are taken into account individually in the estimation of e.s.d.'s in distances, angles and torsion angles; correlations between e.s.d.'s in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell e.s.d.'s is used for estimating e.s.d.'s involving l.s. planes.
Refinement. Refinement of F2 against ALL reflections. The weighted R-factor wR and goodness of fit S are based on F2, conventional R-factors R are based on F, with F set to zero for negative F2. The threshold expression of F2 > σ(F2) is used only for calculating R-factors(gt) etc. and is not relevant to the choice of reflections for refinement. R-factors based on F2 are statistically about twice as large as those based on F, and R- factors based on ALL data will be even larger.
