A new efficient synthesis of 2‐styryl‐6,7‐dichlorothiazolo[4,5‐ b ]quinoxaline based fluorescent dyes was achieved by the condensation of 2‐methyl‐6,7‐dichlorothiazolo[4,5‐ b ]quinoxaline with selected 4‐ N,N ‐dialkylaminoarylaldehydes and heteroarylaldehydes in the presence of piperidine. The coloristic, fluo‐rophoric, and dyeing properties of these dyes were studied.
