The ar-methiodide of quinine type base or of a base in which C9 position of quinine has been substituted by H or Cl, when heated with an aldehyde in EtOH solution, gives a dyestuff in which the loipon portion has separated and C9 combined with the aldehyde in styril type. If OH radical is present at C9, the base undergoes hydramine conversion and does not decompose. Presence of O-acyl radical at C9 results in partial hydramine conversion with some formation of a styril dye. Use of nitroso-aryl, instead of aldehyde, results in a similar decomposition, forming an anil dye corresponding to the styril.
