dc.description.abstract3-Cyano-4,6-dimethyl-2-(1H)-pyridone(III) was treated with phosphorus pentachloride in refluxing phosphorus oxychloride to give 2-chloro-3-cyano-4,6-dimethylpyridine(IV) which was reacted with thioglycolic acid in refluxing methanol in the presence of sodium methoxide to result sodium salt of 3-amino- 4,6-dimethylthieno[2,3-b]pyridine-2-carboxylic acid (V).Various aryl diazonium compounds (VIa-d) were coupled with V to give 3-amino-2-arylazo-4,6-dimethylthieno[2,3-b]pyridines(VIIa-d) with the replacement of carboxylic acid group. The compounds VIIa-d when applied on polyester fibres gave orange to violet shades with excellent pick-up, low light fastness and good to very good sublimation fastness.en_US
