2-Phenylhydrazono-4-thiazolidinone (1) and its 5-substituted derivatives (4) and (6) were cyclized by formaldehyde or aromatic aldehydes to afford the corresponding 2-phenyl-tetrahydrothiazolo[2,3-c]-1,2,4-triazol-5-ones (2, 3) and (7). Compounds 3 were also obtained by the action of aromatic aldehyde on 2-phenyltetrahydrothiazolo[2,3-c]-l2,4-triazol-5-one (2).
