Abstract
The halogenated hydrocarbon amination reaction between the original raw mate-rial N-((6-bromine-2-methoxylquinoline-3-yl)benzyl)-3-chlorine-N-(naphthalene-1-yl)propionamide and morpholine produces the target molecule N-((6-bromine-2-methoxylquinoline-3-yl)benzyl)-3-morpholine-N-(naphthalene-1-yl)propionamide (C34H32BrN3O3,Mr=610.54),and its structure was characterized by 1H NMR,IR,H RMS and X-ray single-crystal diffraction.This crystal is of triclinic system,space group P1 with a=9.315(2),b=10.3449(12),c=15.901(3),α=80.981(14),β=76.996(17),γ=74.917(13)°,V=1433.6(5)3,Z=2,Dc=1.414 g/cm3,F(000)= 632,μ(MoKα)=1.47 mm-1,the final R=0.0735 and wR=0.2457.In total,5585 independent reflections including 3727 observed ones with I 2σ(I) were collected.The dihedral angle between naphthyl and substituted quinolyl and that between phenyl and substituted quinolyl are 61.2(1) and 108.2(1)°,respectively.Through C-H…O and C-H…N hydrogen bonds among molecules,the whole molecule is stacked into a three-dimensional structure.In addition,π-π stacking among adjacent naphthalene rings makes the molecule more stable,and the morpholine ring adopts a chair conformation.The target molecule exhibits good antibacterial activity.
