Abstract

The bromination of 2, 3-dimethylindole in acetic acid followed by hydrolysis has been shown to yield the known dimer 16 of 3-hydroxy-2, 3-dimethylindolenine 15 and not 3- hydroxymethyl-2-methylindole 12 as reported previously by others. Bromination of 2, 3- dimethylindole in the presence of triethylamine has yielded 3-bromo-2, 3-dimethylindolenine 17 as a crystalline solid which is stable at room temperature in a nitrogen atmosphere in ...
