Reaction Steps

A solution of 3-bromobenzene-1-sulfonyl chloride (1.29 g, 5.05 mmol) in 25 mL THF was charged with 2-(pyrrolidin-1-yl)ethanamine (0.6 mL, 5.05 mmol), and TEA (2.2 mL, 15.7 mmol) and allowed to stir for 1 hr. The reaction was quenched with 25 mL NaHCO3 (sat., aq.) and extracted with DCM (2×100 mL). The combined organic layers were washed with brine (20 mL), dried (Na2SO4), filtered, and concentrated. The residue was purified by gradient flash chromatography (0 to 20% MeOH in DCM) to afford the title compound as a white solid (816 mg, 48%).
