Reaction Conditions:
in water; for 3 h;
Steps:
19.b
Ex. 19b. ; To a solution of bromo pyruvic acid (5 g, 30 mmol) in 4 mL water was added ammonium thiocarbamate (Ex. 19a, 3.3 g, 33 mmol). The resulting solution was stirred for 3 h and the solid was collected by filtration. The crude 2-mercaptothiazole-4-carboxylic acid (4.3 g) was used without further purification.
