2-[6,8-Dibromo-3-(4-hy-droxy-cyclo-hex-yl)-1,2,3,4-tetra-hydro-quinazolin-2-yl]phenol methanol 0.25-solvate.
2011
The title compound, C20H22Br2N2O2·0.25CH4O, was synthesized by the condensation reaction of salicylaldehyde with 4-(2-amino-3,5-dibromobenzylamino)cyclohexanol in methanol. There are four independent main molecules and two half-occupied methanol solvent molecules in the asymmetric unit. The dihedral angles between the two benzene rings in the four molecules are 87.8 (6), 86.6 (6), 89.3 (6) and 83.1 (6)°. Each molecule features an intramolecular O—H⋯N hydrogen bond and a short N—H⋯Br link. In the crystal components are linked by O—H⋯O hydrogen bonds.
