aminoalkylbenzotriazoles: Reagents for the aminoalkylation of electron rich heterocycles

Secondary and tertiary aminoalkylbenzotriazoles react with pyrrole, indole, their N-methyl analogs and with 2-methylfuran under mild reaction conditions in the presence of a Lewis acid to afford selectively the corresponding secondary or tertiary amines.

Benzotriazol-1-ylmethylammonium Salts Synthesis and Reactivity

Benzotriazol-1-ylmethylamines on treatment with alkylating agents afford benzotriazol-1-ylmethylammonium salts, also available from reactions of chloromethylbenzotriazole with tertiary amines.In deuterated solvents under basic conditions the methylene protons of these salts exchange with deuterium.At elevated temperatures, an alkyl group substituent migrated from the ammonium center to the benzotriazolyl N-3.Reactions of the salts with Grignard reagents afforded various products arising from substitution of the ammonium moiety and/or from attack on the benzotriazolyl N-3 or on the benzenoid ring.
