Reaction Steps
To a solution of tert-butyl 3-hydroxy-3-(thiophen-3-yl)pyrrolidine-1-carboxylate (5 g, 18.6 mmol) in AcOH (10 mL) and CHCl3 (10 mL) at 0° C. was added NBS (5.0 g, 27.9 mmol) in portions. After stirring for 3 h, the reaction mixture was treated with Na2SO3 and water, followed by extraction with EtOAc. The combined organic layer was washed with brine, and dried over anhydrous Na2SO4. After filtration and concentration, the crude product was purified by column chromatography to give the title compound (5.4 g, 84%).
