2-[6,8-Dibromo-3-(4-hydroxy-cyclo-hexyl)-1,2,3,4-tetra-hydro-quinazolin-2-yl]-6-methoxy-phenol
Abstract:
The title compound, C(21)H(24)Br(2)N(2)O(3), was synthesized by the condensation reaction of 3-methoxy-salicylaldehyde with 4-(2-amino-3,5-dibromo-benzyl-amino)cyclo-hexa-nol in a methanol solution. The dihedral angle between the two benzene rings is 76.4 (3)°. The cyclo-hexyl ring adopts a chair configuration. There is an intra-molecular O-H⋯N hydrogen bond which affects the solid state conformation of the mol-ecule. The crystal structure is stabilized by inter-molecular O-H⋯O hydrogen bonds, forming chains running along the b axis.

Structure and Nomenclature of Alcohols and Phenols
Alcohols are one of the most important functional groups in organic chemistry. The name of alcohol comes from the hydrocarbon from which it is derived. Alcohols are organic molecules containing the functional hydroxyl or –OH group directly bonded to carbon. Phenols have an OH group directly attached to a benzene ring. While alcohols are colorless, phenol is a white crystalline compound with a characteristic "hospital smell" odor.
