Ethyl (2,5-dioxo-1-phenyl-2,3-dihydro-1H,5H-1-benzofuro[3,2-d]imidazo[1,2-a]pyrimidin-3-yl)acetate.

ABSTRACT: In the title compound, C(22)H(17)N(3)O(5), synthesized via the aza-Wittig reaction of ethyl 3-(phenyl-imino-methyl-ene-amino)-benzofuran-2-carboxyl-ate, benzene isocyanate and diethyl 2-amino-succinate, the imidazo[1,2-a]benzo[4,5]furo[2,3-d]pyrim-idine ring system is essentially planar (r.m.s. deviation for all 16 non-H atoms = 0.020 Å). The phenyl ring is twisted with respect to this ring system, making a dihedral angle of 54.23 (4)°. The crystal packing is stabilized by weak inter-molecular C-H⋯O inter-actions.
