The condensation of ethyl o-bromocarbanilate (4) with trimethylsilylacetylene in the presence of dichlorobis(tri-phenylphosphine) palladium, followed by treatment with sodium ethoxide in boiling ethanol gave indole (3a) in 72 % overall yield from 4. Similarly, 2-substituted indoles (3b,c) were synthesized from 4 and the corresponding 1-alkynes.
