Organodilithium reagents derived from 2-alkyl-N-trimethylsilyl anilines undergo condensation with esters of carboxylic acids to afford substituted indoles. A total of 16 examples are reported; yields in general were good. In conjunction with this program, a convenient, large-scale procedure for preparation of monosilylated anilines was also developed. To demonstrate the utility of the new indole protocol
