A variety of 3-substituted indoles are prepared from 1-methyl-3-(benzo
triazol-1-ylalkyl)indoles (1), which are readily available either from
the condensation of 3-methylindole with N-(benzotriazol-1-ylalkyl)car
bamates or from the alkylation and silylation of lithiated 1-methyl-3-
(benzotriazol-1-ylmethyl)indole (2).
