Reaction Steps

step b—To a solution of 345 (2.08 g, 10.70 mmol) in CCl4 (75 mL) was added NBS (2.10 g, 11.80 mmol). The reaction was stirred for 15 min then diluted with a cold 10% aqueous NaHSO3. The reaction mixture was extracted with DCM. The organic extract was washed with brine, dried (MgSO4), filtered and concentrated. The residue was taken up in hexanes (80 mL) and then concentrated to afford 2.9 g (100%) of 344a as a white solid.
