Abstract: The crystal structure of the title compound, C₂₃H₁₇NO₄, is stabilized by intermolecular N-HO and C-HO hydrogen bonds and C-H interactions. The C-HO hydrogen bonds link the molecules into ladders whose uprights form C(7) chains and whose rungs enclose R₂²(28) rings. These motifs generate a three-dimensional network by N-HO hydrogen bonds and C-H interactions. The phthalide ring systems of the molecule are almost planar and form dihedral angles of 64.1 (3) and 88.3 (3)° with the benzene ring.
