3-(2-Aminoethyl)pyrroles are important intermediates for the formation of the 6-azaindole skeleton. It was difficult

to synthesize 3-(2-aminoethyl)pyrroles from pyrrole by Friedel-Crafts alkylation directly because of the inactive site. The electron withdrawing groups were introduced at the α-position of pyrrole to form a positioning effect at the diagonal β-position. With anhydrous AlCl3 as the catalyst, nitroalkenes could be added to the 3-position of pyrrole via Friedel-Crafts alkylation to obtain substituted 3-(2-aminoethyl)pyrroles.

Key words: Keywords aluminium chloride, 3-(2-aminoethyl)pyrrole, 6-azaindole
