Thioamide examples
WebFor example, cyclocondensation of thioamide 2 with ethyl 3-bromo-2-oxopropanoate under basic conditions provides the hydroxythiazoline intermediate 3 (15MCC300). The thiazoline is then dehydrated using trifluoroacetic anhydride (TFAA) and pyridine followed by triethylamine to form the monothiazole 4 in good yield (74% for two steps).
