Fischer, Gerhard W.
, p. 1557 - 1562 (2007/10/03)
The acid-catalyzed reaction of substituted phenylhydrazines 1 with 1-aryl-5-(2-dimethylaminovinyl)-1H-tetrazoles 2 afforded (1-aryl-1H-tetrazol-5-yl)acetaldehyde phenylhydrazones 3 which on heating in acetic acid/perchloric acid underwent a Fischer indoli
