The title compound, C₁₄H ₁₇N₃ O, prepared from (1R,2S)-
(-)-ephedrine, crystallizes in space group P2₁ with four
molecules in the asymmetric unit. The molecules, in
pairs, take part in intermolecular N--H...N hydrogen bonding between the imidazolyl rings, forming one-dimensional
chains with alternating N...N distances of
2.866 (3)/2.883(3) and 2.945 (3)/2.956(3)Å. Inter-chain
Carene--H...πarene, Carene--H...O and Csp3--H...πc=
interactions generate a three-dimensional network.
