2-[3-Meth­oxy-5-(pyrimidin-2-yl)phen­yl]pyrimidine

The title compound, C₁₅H₁₂N₄O, was synthesized by a standard Suzuki cross-coupling reaction. The terminal pyrim­idine rings are rotated at dihedral angles of 12.06 (4) and −13.13 (4)° with respect to the central benzene ring. In the crystal, the mol­ecules are connected by two kinds of C—H...N hydrogen bonds, forming zigzag chains along the c axis. Weak π–π inter­actions between the benzene and one of the pyrimidine rings are also found and stack the mol­ecules along the b axis [centroid–centroid distance = 4.112 (3) Å].

(Z)-3β-(2-Chloro­anilino)-17(20)-pregnene

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 intra­molecular N—H...Cl hydrogen bond. The crystal packing exhibits no short inter­molecular contacts.
