Abstract

The crystal structure of the title compound, C(26)H(25)NO(3), was determined as part of an investigation of host-guest and electron donor-acceptor complexes. The oxazole and the pyrrole rings both adopt envelope conformations. The dihedral angle between the two benzene rings directly linked to the oxazole ring is 49.5 (1)°. The crystal structure is stabilized by a C-H⋯π inter-action.
