2-Methylindole is used as a reactant for regioselective synthesis of oxopyrrolidine analogs via iodine-catalyzed Markovnikov addition reaction, Friedel-Crafts alkylation reactions, preparation of tryptophan dioxygenase inhibitors pyridyl-ethenyl-indoles as potential anticancer immunomodulators, Michael addition reactions and in synthesis of cyclooxygenase-1 (COX-1)/cyclooxygenase-2 (COX-2) inhibitors.
This Thermo Scientific Chemicals brand product was originally part of the Alfa Aesar product portfolio. Some documentation and label information may refer to the legacy brand. The original Alfa Aesar product / item code or SKU reference has not changed as a part of the brand transition to Thermo Scientific Chemicals.

- An alternative approach to functionalization of the 2-methyl group involves low-temperature N-lithiation followed by reaction with dimethyl carbonate to give the 1-methoxycarbonyl derivative.
