Participants

Reaction Steps

A solution of (±)-(2S,3R,5R)-1-benzyl-2-vinyl-3-(hydroxymethyl)-pyrrolidine-5-carboxylic acid t-butyl ester (3.6 g, 11.4 mmole), tert-butyldimethylsilyl chloride (3.7 g, 24.5 mmole) and imidazole (2.8 g, 41.2 mmole) in 60 mL of DMF was stirred at room temperature for 1.5 hours. The reaction was diluted with ethyl acetate, washed with water and brine, dried over MgSO4, and concentrated in vacuo. The residue was purified by chromatography on silica gel using 5% ethyl acetate/hexanes to provide the title compound, as a colorless oil (yield: 3.5 g, 71%).
