Reaction Steps

A solution of 11.0 g (0.05 mole) 5-amino-3-trichloromethyl-1,2,4-thiadiazole and 14.1 g (0.1 mole) benzoyl chloride in 200 ml xylene was heated at reflux for 20 hours. Upon cooling to -10° C., 13.7 g (85% yield) of pure product precipitated from the reaction mixture and was isolated by filtration; m.p. 190° C.
