実験手順

To a stirring solution of (S)-3-[4-(3,4-dichloro-benzyloxy)-phenyl]-1,2,3,5,7,8-hexahydro-4-oxa-1,6-diaza-anthracene-6,7-dicarboxylic acid 6-tert-butyl ester (146 mg), HBTU (95 mg) and DIEA in DMF (5 mL) was added (S)-2-amino-3-(4′-cyano-biphenyl-4-yl)-propionic acid methyl ester (79 mg). After 4 hours, a sufficient amount of water was added and the mixture extracted with ethyl acetate. The organic layer was washed with 1 N HCl, saturated NaHCO3 and brine, and dried over sodium sulfate. The solvent was removed under reduced pressure to provide the crude amide. The residue was purified by column chromatography on silica gel (hexanes/ethyl acetate from 80:20 to 60:40) to give the product (169 mg).
