%X In the title compound, C22H17N3O5, synthesized via the aza-Wittig reaction of ethyl 3-(phenyliminomethyleneamino)benzofuran-2-carboxylate, benzene isocyanate and diethyl 2-aminosuccinate, the imidazo[1,2-a]benzo[4,5]furo[2,3-d]pyrimidine ring system is essentially planar (r.m.s. deviation for all 16 non-H atoms = 0.020  ). The phenyl ring is twisted with respect to this ring system, making a dihedral angle of 54.23 (4)¡ã. The crystal packing is stabilized by weak intermolecular C¡ªH...O interactions.
