Reaction Steps

To a mixture of 2-amino-5-(4-pyridylthio)thiazole (2.5 g) and pyridine (3 g) in N,N-dimethylformamide (25 ml) was added dropwise the 4-fluorobenzoyl chloride (2.7 g) at 5° C. under ice cooling with stirring. The mixture was stirred at 5° C. for 4 hours under ice cooling. 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-(4-fluorobenzoylamino)-5-(4-pyridylthio)thiazole (2.5 g, yield: 63.1%). mp: 220°-225° C. (dec.)
