The title compound, C(18)H(15)NO(3), consists of an indolizine ring system and an aromatic ring. The two ring systems are not coplanar, the dihedral angle between the two being 54.26 (7)°. In the crystal, inversion dimers are formed by weak C-H⋯O interactions. These dimeric groups are further extended to form a regular two-dimensional structure by additional weak C-H⋯O inter-actions.
