title: 3,3'-(1,4-Phenyl-ene)bis-[2-(propyl-amino)-benzofuro[3,2-d]pyrimidin-4(3H)-one] ethanol disolvate.
abstract: The title compound, C(32)H(28)N(6)O(4)·2C(2)H(5)OH, consists of two 2-(propyl-amino)-benzofuro[3,2-d]pyrimidin-4(3H)-one units connected, via one of the pyrimidine N atoms, to a bridging benzene ring in the 1,4 positions. Two ethanol solvent mol-ecules are also present. The main mol-ecule lies on a center of symmetry located at the center of the benzene ring. The fused-ring system of the benzofuro[3,2-d]pyrimidine moiety is nearly planar (r.m.s. deviation = 0.016 Å) and forms a dihedral angle of 78.21 (7)° with the central benzene ring. The crystal structure features O-H⋯O and N-H⋯O inter-actions. The C atoms of the propyl-amino side chain in the main mol-ecule and the ethyl group in the solvent mol-ecule are disordered over two positions, with site-occupancy factors 0.34:0.66 and 0.42:0.58, respectively.
