Reaction Conditions

Reaction Steps

A solution of potassium hydroxide (3.30 g.) in water (7 ml.) was added to a solution of ethyl 1,2,3-thiadiazole-5-carboxylate (8.00 g.) in ethanol (25 ml.). The mixture was stirred at 23° C. for 2 hours, and then was worked up to yield potassium 1,2,3-thiadiazole-5-carboxylate. A suspension of this salt (3.00 g.) in toluene (25 ml.) was treated at 0° C. with oxalyl chloride (1.6 ml.), stirred at 0° C. for 1 hour, and then was worked up to yield 1,2,3-thiadiazole-5-carbonyl chloride.
