Participants

Reaction Steps

A solution of methyl 1-tert-butoxycarbonyl-4-methylindole-2-carboxylate (0.13 g, 0.48 mmol), NBS (0.087 g, 0.48 mmol), and AIBN (4 mg, 0.024 mmol) in carbon tetrachloride (1.9 mL) was heated to reflux for 3 h. The reaction mixture was cooled to room temperature and filtered and washed with carbon tetrachloride. The filtrate was evaporated to give a yellow oil that was purified by silica gel chromatography (EtOAc:hexane=8:92) to give 0.12 g (72% yield) of the title compound as a pale yellow solid:
