Reaction Steps

To a solution of 3-methyl-4-(1H-pyrrol-1-yl)benzamide (6A, see first step of Scheme 6 for synthesis) in DMF (5 mL) was added N-bromosuccinimide (177 mg, 1 mmol) portionwise at 0° C., after the addition was completed, the mixture was stirred at room temperature for 35 min. The reaction mixture was poured into water, and extracted with ethyl acetate (10 mL×3). The combined organic layers were washed with brine (25 mL×2), dried over anhydrous sodium sulfate, filtered, and concentrated under reduced pressure. The residue was purified by column chromatography on silica gel (petroleum ether/ethyl acetate=5:1) to afford 50B (100 mg, yield 36%).
