Indolylcarboxylate esters 2 and 2-substituted 3-benzylindoles 4 are prepared usually in good yield through the palladium-catalyzed reaction of o-alkynyltrifluoro acetanilides with ethyl iodoacetate or benzyl bromide. Best results are obtained by employing Pd2(dba)3 and tris(2,4,6-trimethoxyphenyl)phosphine in THF.
