Abstract: The title compound, C₂₀H₂₅NO₂, a condensation product of l-ephedrine and 4-propoxyaldehyde, is of interest in studies on weak interactions. It crystallizes with C-HO and C-H(arene) intermolecular interactions as a one-dimensional chain [CO = 3.3745  (19)  Å, C-HO = 139°; C-HCg1 = 3.6987  (16)  Å, C-HCg1 = 161°, where Cg1 is the centroid of the symmetry-related 4-propoxy-substituted aromatic ring].
