実験手順
122 mg (3R/S,5S)-5-Biphenyl-4-ylmethyl-2-oxo-3-(toluene-4-sulfonyloxymethyl)-pyrrolidine-1-carboxylic acid tert-butyl ester (11-a, R1=Boc, R4=Tosyl) prepared according to Example 49, Method 2 is added to acetonitrile (3 ml). Sodium iodide (105 mg) is then added to the mixture. The resulting mixture is heated at reflux overnight. The mixture is then concentrated under reduced pressure. Purification by column chromatography, eluting with ethyl acetate-heptane (1:1) gives (3R/S,5S)-5-biphenyl-4-ylmethyl-3-iodomethyl-pyrrolidin-2-one (12-a, R1=H, R5=I). 1H NMR (CDCl3): 2.13 (2H), 2.69 (2H), 2.82 (1H), 3.28 (1H), 3.35 (1H), 3.85 (1H), 5.84 (1H), 7.17 (2H), 7.28 (1H), 7.37 (2H), 7.49 (4H).
