A modified Madelung synthesis for the conversion of N-(alkylphenyl)alkanamides and related compounds to indoles, benzindoles, and azindoles has been developed.This procedure consists of treating the amide with 2 or 3 equiv of n-butyllithium or lithium diisopropylamide in tetrahydrofuran at temperatures from -20 to +25 deg C.Several examples where products other than indoles were formed from the starting amide are also reported.
