The title compound, C32H28N6O4·2C2H5OH, consists of two 2-(propylamino)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 molecules are also pr

In the title compound, C20H22N2O2S, the central thienopyrimidine ring system is essentially planar, with a maximum displacement of 0.023 (2) Å. The attached cyclohexene ring is disordered over two possible conformations, with an occupancy ratio of 0

In the title compound, C12H13ClN4O2, the triazole ring carries methyl and ethoxycarbonyl groups, and is bound via a methylene bridge to a chloropyridine unit. There is evidence for significant electron delocalization in the triazolyl system. Intramol

In the title compound, C19H12N2O3, the 1-benzofuro[3,2-d]pyrimidinone unit is approximately planar, the maximum deviation from the mean plane being 0.045 (1) Å. The attached phenyl ring makes a dihedral angle of 86.73 (6)° with the fused ring syste
