実験手順
11.8 g of 5-methylthio-1,3,4-thiadiazole-2-carboxylic acid ethylester which is the compound obtained in Example 10, were mixed with 50 ml ethanol and 50 ml of a 25% aqueous ammonia solution whereupon the mixture was heated for 15 minutes on a steam bath. After cooling part of the reaction product precipitated. The precipitation was completed by adding ice water. The precipitate was then removed by suction and dried in a vacuum.
