Participants

Reaction Steps

To a stirred solution of 561 mg of tert-butyl 2-cyano-4-methoxy-5-methyl-1H-indole-1-carboxylate (1.96 mmol) in carbon tetrachloride (9 mL) was added 349 mg of N-bromosuccinimide (1.96 mmol) and 64 mg of AIBN (0.39 mmol). The mixture was refluxed for 1 h, then cooled and concentrated and filtered through short silica gel plug using hexane-ethyl acetate 10:1 to give 852 mg of crude tert-butyl 5-(bromomethyl)-2-cyano-4-methoxy-1H-indole-1-carboxylate that was used in the next step without further purification.
