TETRAZOLYLPHENYLBORONIC ACID INTERMEDIATES FOR THE SYNTHESISOF AII RECEPTOR ANTAGONISTS

摘要

Novel tetrazolylphenylboronic acids, methods for their preparation and methods f or preparing biphenyltetrazole compounds which are antiotensin II receptor antagonists or which are useful inte rmediates to prepare angiotensin II receptor antagonists. An illustrative biphenyl tetrazole compound is 2-n-butyl-4-chloro-1 -¢(2'-(tetrazol-5-yl)-1,1'-biphenyl-4-yl)methyl!-1H-im-idazole-5-methanol, potassium salt.
