YieldReaction ConditionsOperation in experiment
77% With triethylamine; In N,N-dimethyl-formamide; for 2.25h; EXAMPLE lO[D-(+)-biotinyl]-L-aspartate alpha-benzyl ester (14)To a suspension of D-Biotin (2.0 g, 8.19 mmol) in DMF (52 mL) was added pentafluorophenol (1.6 g, 15.6 mmol) followed by DCC (2.5 g, 12.3 mmol). The reaction mixture was allowed to stir, under nitrogen atmosphere, overnight at RT. The reaction mixture remained a suspension and was filtered off and concentrated. The residue was taken up into Et2theta and stirred for several minutes after which the suspension was filtered an dried und vacuum to give a white solid (2.58 g) ESI-MS: 411 [M+H]+. The solid was dissolved in DMF (90 mL) and Et3N (1.24 mL, 8.82 mmol, 1.4 equiv.) was added. H-Asp-OBn was added in portions as a solid. After approximately 15 min the reaction mixture became clear and an additional 2h stirring was allowed. The reaction mixture was concentrated under reduced pressure and water was added followed by MeOH (3:1). The solid formed was filtered off, washed with Et2theta and dried under vacuum to give compound 14 as a white solid (2.92 g, 77 %) ESI-MS: 450 [M+H]+.
