Ethyl 2-[1-(4-chlorophenyl)-2,5-dioxo-1,2,3,5-tetrahydroimidazo[1′,2′:1,2]pyrimidino[5,4-b][1]benzofuran-3-yl]acetate
The asymmetric unit of the title compound, C22H16ClN3O5, consists of two crystallographically independent molecules. The fused rings of the imidazo[1,2-a]benzo[4,5]furo[3,2-d]pyrimidine system are nearly coplanar and the chlorophenyl rings are twisted with respect to the two pyrimidinone ring system...
