The cyclization of 2,4,6-trimethoxyacetophenone phenylhydrazone was studied. When using PPA as catalyst the main product proved to be 4,6-dimethoxy-3-methyl-1-phenylindazole while 2-(2,4,6-trimethoxy)indole was obtained in good yield when the reaction was carried out in the presence of anhydrous zinc chloride. The reaction mechanism is discussed.
