By the reaction of the anilide of thiocarbonyl tetrachloride and quinaldine ethiodide, a new dye, 1, 1′, 1″-triethyl-2, 2′-trimethine-10-anilinoquinolinium iodide was prepared. Application of another mole of quinaldine ethiodide to the latter gave 1, 1′, 1″-triethyl-2, 2′-trimethine-10-quinaldenyl-cyanine iodide, and application of lepidine or 2-methyl-benzothiazole ethiodide gave pinacyanol, with heterocyclic ammonium salt in the 10-position, i.e. a new trimethine dye with three different nuclei.
