Abstract: 4,5-Disubstituted thiazoles are manufactured by reacting 4-amino-5-cyano-thiazoles with hydrogen sulfide in the presence of basic compounds, followed by dehydrogenating cyclization. The new 3-amino-thiazolo-(4,5-c)-isothiazoles I, 4-amino-5-thiocarbamidothiazoles III and 4,5-disubstituted thiazoles IV obtainable by the process of the invention are valuable intermediates for the manufacture of azo dyes and of crop protection agents.
