Convergent Synthesis of Angiotensin II Receptor Blockers through C-H Arylation of 1-Benzyl-5-phenyl-1 H -tetrazole with Functionalized Aryl Bromides
Highly convergent synthesis of angiotensin II receptor blockers has been accomplished by means of late-stage C-H arylation using functionalized aryl bromides. C-H arylation of 1-benzyl-5-phenyl-1 H -tetrazole with aryl bromides carrying methyl 2-ethoxyben
