Reaction Steps

A solution of 5-methyl-1,3,4-thiadiazole-2-thiol (264 mg, 2 mmol) and ethyl bromopyruvate (0.264 mL, 2.1 mmol) in methylene chloride (10 mL) and acetonitrile (10 mL) was stirred at 20° C. for 3 hours under nitrogen. The precipitates were filtered, washed with methylene chloride, and dried under vacuum. This gave the expected product, 3-(5-methyl-[1,3,4]thiadiazol-2-ylsulfanyl)-2-oxo-propionic acid ethyl ester (450 mg, yield 69%) as a solid.
