摘要:
A process for the direct preparation of pure thiazolazo compounds had been found with the use of a 2-aminothiazole as diazo or azo component in a coupling process wherein the 2-aminothiazole used therein is subjected to the usual coupling reaction, if used as diazocomponent after diazotation, without intermediate isolation after its preparation in known manner. This process avoids the preparation of the 2-aminothiazoles as starting compounds in its solid form and the expensive purification of these instable compounds and yields now very pure azo products.
