RING CONTRACTION OF THIA(SELENO)DIAZINE RINGS INTO PYRAZOLES IN THE REACTION OF 3-ARYL-10-METHYL-1H-1,3,4-THIA(SELENO)DIAZINOBENZIMIDAZOLIUM SALTS WITH BASES

Reaction of 3-aryl-10-methyl-2H-1,3,4-thiadiazinobenzimidazolium salts with triethylamine led to ring contraction of the thiadiazine ring to a pyrazole ring with the formation of a mixture of derivatives of 3-mercaptopyrazolobenzimidazole and di(py

SYNTHESIS OF 4-ALKYLPYRAZOLOBENZIMIDAZOLES

2,4-Disubstituted pyrazolobenzimidazoles were obtained by the action of carboxylic acid anhydrides on 1-amino-2-methyl-3-alkylbenzimidazolium salts in the presence of potassium carbonate.
