Abstract
The title compound, C(25)H(31)NO(2).H(2)O, has the outer two six-membered rings in chair conformations, while the central ring is in an 8beta,9alpha-half-chair conformation. The five-membered ring adopts a 13,14-half-chair conformation. The pyridylmethylene moiety has an E configuration with respect to the carbonyl group at position 17. The structure is stabilized by intermolecular O-H...N and O-H...O hydrogen bonds.
