title: (Z)-5-Benzyl-idene-3-butyl-4-phenyl-1,3-oxazolidin-2-one.
abstract: In the title compound, C(20)H(21)NO(2), the benzyl group and the oxazolidin-2-one unit are each essentially planar, with maximum deviations of 0.026 (2) and 0.031 (2) Å, respectively. The dihedral angle between the phenyl ring and the oxazolidin-2-one unit is 69.25 (2)°. In the crystal, mol-ecules are linked by weak inter-molecular C-H⋯O and C-H⋯π inter-actions.
