Abstract
The halogenated hydrocarbon amination reaction between the original raw material N-((6-bromo-2-methoxyquinolin-3-yl)(phenyl)methyl)-3-chloro-N-(1-adamantyl) propanamide and dimethylamine hydrochloride produces the target molecule N-((6-bromo-2-methoxyquinolin-3- yl)(phenyl)methyl)-N-(1-adamantyl)-3-(dimethylamino) propanamide (C32H38BrN3O2, Mr = 576.56), and its structure was confirmed by elemental analysis, IR, 1H NMR, MS, and X-ray diffraction. This crystal is of monoclinic system, space group P21/c with a = 10.760(5), b = 14.768(5), c = 19.635(5), β = 113.969(16)°, V = 2851.0(18)3, Z = 4, Dc = 1.343 g/cm3, F(000) = 1208, μ(MoKα) = 1.475 mm–1, the final R = 0.0645 and wR = 0.2039. In total, 4681 independent reflections including 3164 observed ones with I 2σ(I) were collected. The dihedral angle between substituted quinolyl and phenyl is 64.0°. Through C–H···O, C–H···N and C–H···Br weak hydrogen bonds among molecules, the whole molecule is stacked into a three-dimensional structure. The optimized geometric bond lengths and bond angles obtained by using density functional theory (DFT) have been compared with X-ray diffraction values. In addition, the preliminary biological test showed that the title compound has anti-Mycobacterium phlei 1180 activity.
