摘要:Disclosed is a process for forming a 1H-pyrazolo (1,5-b)-[1,2,4]-triazole compound by ring closing a pyrazoloamidine compound comprising reacting the amidine with an oxidizing agent having a reduction potential vs Ag/AgCl that is more positive than -0.16V and less than +1.43V in the presence of a halogen atom. The invention also discloses certain triazole compounds that are successfully made by the conventional process. The process and compounds of the invention provide improved yields and reduce or eliminate unwanted side-reactions.
