Reaction Steps

(3S,4R)-1-Benzyloxycarbonyl-4-[1-(hydroxymethyl)vinyl]pyrrolidine-3-carboxylic acid tert-butyl ester (30.0 g, 83.0 mmol) was dissolved in dichloromethane (300 mL). Triphenylphosphine (23.2 g, 87.2 mmol) and carbon tetrabromide (29.4 g, 87.2 mmol) were added, and the mixture was stirred at room temperature for 30 minutes. The reaction solution was concentrated under reduced pressure. Then, the resulting residue was purified by silica gel column chromatography (hexane:ethyl acetate=100:1→1:1) to give 26.9 g of the title compound as a colorless oil.
