4. Synthesis of new trisubtitued imdidazole compounds in solvent free condition

Omid Baravaye

Volume 7, Issue 4 , Autumn 2017, Pages 29-37

Abstract
  Treatment of 7-chloro-1-phenylpyrimido[4,5-e][1,3,4]thiadiazines with hydrazine in boiling ethanol gave corresponding7-hydrazinyl derivatives. Diazotization of the latter compounds acheived a mixture of 5H-tetrazolo[1',5':1,2]pyrimido[4,5-e][1,3,4]thiadiazine and 9H-tetrazolo[5',1':2,3]pyrimido[4,5-e][1,3,4]thiadiazines. ...  Read More
