Reaction Steps

To a solution of ethyl 2-methyl-1H-pyrrole-3-carboxylate (1.53 g) in tetrahydrofuran (20 mL) was added N-bromosuccinimide (1.78 g) at −78° C., and the mixture was stirred at the same temperature for 30 min. Water and diethyl ether were added to extract the reaction mixture. The extract was washed with saturated brine, dried over anhydrous magnesium sulfate, and concentrated under reduced pressure at 5° C. or below. The residue was washed with hexane to give the title compound as a colorless solid (yield 2.26 g, 97%).
