Vilsmeier-Haack reaction of 2,3,3-trimethyl-3 H -benzo[ g ]indole, then aqueous basic work-up, leads to benzo[g]indol-2-ylidene- malondialdehydes. These react with various arylhydrazines and quinolin-2-ylhydrazine to form 3,3-dimethyl-2-(1-aryl-1 H -pyrazol-4-yl)- 3 H -benzo[ g ]indoles in good yields.
