Reaction Steps

To 2-AMINOTHIAZOLE (1.80 g, 0.0179 mol) in Pyridine (6 mL, 0.08 mol) at 0° C. was added 2-Chloropyridine-5-sulfonyl chloride (1.55 g, 0.00717 mol) portion-wise. The reaction mixture was stirred overnight at room temperature. The reaction mixture was concentrated under reduced pressure, diluted with ethyl acetate (150 mL), washed with water and brine. The organic phase was dried over anhydrous sodium sulfate, filtered and concentrated. The crude product was purified on ISCO companion (silica gel, 10% to 100% ethyl acetate in hexanes) to give product as a brown solid.
