The crystal packing of the title compound, C13H19NO·0.33C7H8, shows a channel at , which contains grossly disordered toluene solvent molecules. The angle between the benzene ring and the mean plane of the formamide group is 71.1 (1)°. The amide groups of neighbouring molecules are connected by N—H⋯O hydrogen bonds, forming 21 helical chains propagating along . Molecules are also connected by weak intermolecular C—H⋯O hydrogen bonds, forming 61 helices.
