反応手順
In 200 ml of water were dissolved 15.0 g of 2,5-dimercapto-1,3,4-thiadiazole and 69 g of potassium hydroxide, and a solution of 13.9 g of bromoacetic acid in 30 ml of water was added thereto dropwise at room temperature. After the addition, the mixture was stirred at 60° C. for 1 hour, followed by allowing to cool to room temperature. The precipitated crystals were filtered and washed with water to obtain 18 g of the desired compound. Melting point: 161°-167° C.
