Participants

Reaction Steps

A mixture of the intermediate from Step B (0.322 g, 1.903 mmol), NBS (0.373 g, 2.09 mmol), and AIBN (0.016 g, 0.095 mmol) in 15 mL of CCl4 was refluxed for 1 hour. The mixture was cooled to room temperature, filtered, and concentrated. The residue was purified by silica gel chromatography using a hexanes/EtOAc gradient to give a 7:1 mixture of the indicated product and methyl 2-bromo-2-[4-(bromomethyl)-1,3-oxazol-2-yl]propanoate (pale yellow oil). The mixture was used in the next step without further purification.
