2′-Methyl­pyrazolo[4′,3′:16,17]androst-5-en-3β-ol

In the title compound, C(21)H(30)N(2)O, there are five fused rings. The A and C rings adopt chair conformations, ring B adopts an 8β,9α-half-chair conformation and ring D adopts a 14α-envelope conformation. The pyrazole ring is planar. Inter­molecular O—H⋯N hydrogen bonds [H⋯N = 1.88 (5) Å] help to...

Inter­molecular O—H⋯N hydrogen bonds [H⋯N = 1.88 (5) Å] help to stabilize the crystal structure. The absolute structure was deduced from those of the starting materials.
