The crystal packing of the title compound, C13H19NO·0.33C7H8, shows a channel at [001], 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 [001]. Mol­ecules are also connected by weak inter­molecular C—H⋯O hydrogen bonds, forming 61 helices.
