Reaction Steps
In analogy with Example 1b), 1.5 g of 5(S)-[1(S)-(Boc-amino)-2-phenylethyl]dihydrofuran-2-(3H)-one, dissolved in 32 ml of THF, are deprotonated with 9.8 ml of a 1M solution of lithium bis(trimethylsilyl)amide in THF, and alkylated with 1.0 g of 4-bromomethylbenzonitrile (Fluka; Buchs/Switzerland) dissolved in 3 ml of THF. Column chromatography (SiO2, hexane/ethyl acetate 1:1) affords the pure title compound: TLC Rf (D)=0.33.
