反応手順
2-Hydrazinobenzothiazole (100 grams) and urea (100 grams) were fused on an oil bath at about 180° C. for about an hour, by which time the molten material had solidified and evolution of ammonia had ceased. The solid thus obtained, the desired s-triazolo(3,4-b)benzothiazol-3-ol, was recrystallized twice from methanol, m.p., 235° C.
