2-(3-Methyl-3H-imidazole-4-yl)quinoline

An imidazoylquinoline alkaloid, this base occurs in Macrorungia longistrobus C.B. Cl. It may be crystallized from Me2CO-hexane as colourless needles. In neutral solution (EtOH) the ultraviolet spectrum exhibits absorption maxima at 214,235,279,328 and 342 mJ1; while in acid solution (EtOH-HCl), the absorp_x0002_tion maxima occur at 218, 252, 292, 319 and 334 mJ1. The alkaloid has been characterized as the crystalline perchlorate with m.p. 209°C (dec.). The methiodide is identical with macrorine methiodide, m.p. 196°C (dec.). The structure has been determined from chemical degradation and spectroscopic analysis as l' -methyl-2: 5' -( 1 'H-imidazoyl)quinoline.
