A novel efficient synthesis of 2‐styrylthiazolo[4,5‐ b ]quinoxaline based fluorescent dyes was achieved by the condensation of 2‐alkylthiazolo[4,5‐ b ]quinoxaline with selected 4‐ N,N ‐dialkylamino‐substituted aryl‐aldehydes or hetarylaldehydes in the presence of piperidine or acid anhydride. The coloristic, fluorophoric and dyeing properties of these dyes were studied.
