A synthesis of 1-hydroxy-5-(2-substituted aryl)tetrazoles by directed lithiation

Dilithiation of 1-hydroxy-5-aryltetrazoles with 2 equiv. of butyllithium in the presence of N,N,N′N′-tetramethylethylenediamine enables the introduction of ortho-substituents into the aryl ring to form compounds (6a-e). The hydroxy group of 1-hydroxy-5-ph
