【 摘 要 】

In the title compound, C23H24BrNO5, the central 1,4-di­hydro­pyridine ring of the 1,2,3,4,5,6,7,8,9,10-deca­hydro­acridine ring system adopts a half-chair conformation. The two cyclo­hexene rings fused to the central ring both have a twisted-boat conformation. The mean planes of the bromo­hydroxy­phenyl ring and the major and minor components of the disordered ethyl amino­acetate moiety make dihedral angles of 78.99 (12), 85.9 (2) and 88.3 (9)°, respectively, with the 1,4-di­hydro­pyridine ring. The terminal ethyl group of the ethyl amino­acetate moiety is disordered over two sets of sites with refined occupancies of 0.768 (17) and 0.232 (17). The mol­ecular conformation is stabilized by an intra­molecular O—H⋯O hydrogen bond, forming an S(8) ring motif. In the crystal, C—H⋯O hydrogen bonds connect the mol­ecules into layers parallel to (001), enclosing R12(7) ring motifs.
