Participants

Reaction Steps

To a solution of 4-(4-methoxybutoxy)benzonitrile (21.8 g) and trifluoroacetic acid (109 ml) in toluene (218 ml) was added thiosemicarbazide (11.62 g). The solution was stirred for 31 hours at 60° C., during which period additional thiosemicarbazide (2.90 g) and trifluoroacetic acid was added to the mixture. The reaction mixture was pulverized with ethyl acetate. The precipitate was collected by filtration and dried to give 5-[4-(4-methoxybutoxy)phenyl][1,3,4]thiadiazol-2-ylamine trifluoroacetic acid salt (15.10 g).
