The title compound 1-(2-(3,5-di-tert-butyl-4-hydroxyphenyl)-2-oxoethyl) quinolin-1-ium bromide was obtained in good yield by a facile one-pot, one-step synthetic procedure involving quinoline and an aromatic α-bromo ketone. The product was isolated using hot recrystallization from acetone/acetonitrile solution and characterized using powder and single-crystal XRD, 1D and 2D NMR, DSC, FT-IR, and HRMS analyses.
