Abstract
By means of the Grignard reaction between pyrrolmagnesium iodide and phthalic anhydride in anisole, o-(pyrroyl-2) benzoic acid was formed which, after benzylation at the nitrogen atom by the action of phosphorous pentoxide, was converted into 1-benzyl-4, 9-diketo-4, 9-dihydrobenzo[f]indole.
