3′-(4-Methoxyphenyl)-4′-phenyl-3H,4′H-spiro[1-benzothiophene-2,5′-isoxazol]-3-one

In the title compound, C23H17NO3S, the thiophene and isoxazole rings each have an envelope conformation with the spiro C atom linking them forming the flap of the envelope in each case. The dihedral angle between the mean planes of the benzothiophene ring and isoxazole rings is 81.35 (7)°. In the crystal, an intermolecular C—H⋯O hydrogen bond links the molecules into a chain running parallel to the a axis.
