چکیده
In the title mol-ecule, C(22)H(15)NO(3), the configuration about the ethyl-enic double bond is Z configuration and it is approximately coplanar with the adjacent phenyl ring and benzoxazole ring system as indicated by the C(H)=C(O)-C(phen-yl)-C(phen-yl) and O(benzoxazole)-C-C(H)=C(O) torsion angles of 179.88 (15) and 5.7 (2)°, respectively. The dihedral angle between the essentially planar (r.m.s. deviation = 0.080 Å) 2-(1,3-benzoxazol-2-yl)-1-phenyl-ethenyl group and the benzoate phenyl ring is 61.51 (6)°. A short intra-molecular O⋯O non-bonded inter-action of 2.651 (2) Å is present.
