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 was added to the reaction mixture, and the mixture was extracted with diethyl ether. The extract was washed with saturated brine, dried over anhydrous magnesium sulfate, and concentrated under reduced pressure at not more than 5° C. The residue washed with hexane to give the title compound as a colorless solid (yield 2.26 g, 97%).
