Procedure

To a stirring solution of (S)-3-[4-(3,4-dichloro-benzyloxy)-phenyl]-1-methyl-1,2,3,5,7,8-hexahydro-4-oxa-1,6-diaza-anthracene-6,7-dicarboxylic acid 6-tert-butyl ester, 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 was extracted with ethyl acetate. The organic 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 afford the product (180 mg).
