Potassium Carbonate → 2-Amino-4-(4-nitrophenylthiomethyl)thiazole

Participants

Reaction Steps

A mixture of 4-nitrothiophenol (9.3 g), 2-amino-4-chloromethylthiazole hydrochloride (11 g) and potassium carbonate (20 g) in N,N-dimethylformamide (200 ml) was heated at 85°-90° C. for 5 hours with stirring. The reaction mixture was concentrated under reduced pressure and the residue was triturated with water. The precipitates were collected by filtration, washed with water and dried in vacuo to give 2-amino-4-[4-nitrophenylthiomethyl)thiazole (15.80 g, yield: 98.6%).
