Reaction Steps
0.38 g of 2-[(4-fluorophenyl)acetyl]hydrazinecarbothioamide (1.67 mmol) is added portionwise with stirring. After stirring for 3 hours between 0 and −10° C., water is added dropwise and the mixture is then returned to basic pH with sodium hydroxide, while maintaining a temperature of between 0 and −10° C. The precipitate is filtered off, washed with water and dried. 0.264 g of 5-(4-fluorobenzyl)-1,3,4-thiadiazol-2-amine is obtained.
