PROCEDURE
实验过程
(S)-3-[4-(3,4-Dichloro-benzyloxy)-phenyl]-2,3,8,9-tetrahydro-6H-[1,4]dioxino[2,3-g]isoquinoline-7,8-dicarboxylic acid 7-tert-butyl ester, HBTU and DIEA were dissolved in DMF (20 mL). (S)-2-Amino-3-(4′-cyano-biphenyl-4-yl)-propionic acid methyl ester was added and the mixture stirred at r.t. for 16 h. The reaction mixture was poured into 1 N HCl and extracted with ethyl acetate. The organic extracts were combined and washed with 1 N HCl and 10% sodium carbonate, concentrated and purified by column chromatography on silica gel (hexanes-ethyl acetate) to afford the product (4.9 g). LCMS (m/z) 851.
