実験手順

Suzuki Coupling. To a solution of (S)-3-(4-Bromo-phenyl)-2-tert-butoxycarbonylamino-propionic acid methyl ester in toluene (250 mL) was added 4-cyanobenzeneboronic acid, Pd(PPh3)4, and 1N Na2CO3 solution (105 mL). The mixture was heated at reflux for 7 h. After completion of the reaction, the aqueous layer was drained. The organic layer was washed with 10% Na2CO3 and 1 N HCl. The organic layer was dried over sodium sulfate and concentrated under reduced pressure to afford the crude product. The residue was then purified by column chromatography (hexanes-EtOAc) to provide (S)-2-tert-Butoxycarbonylamino-3-(4′-cyano-biphenyl-4-yl)-propionic acid methyl ester (18.2 g). LCMS (m/z) 382.
