PROCEDURE
实验过程
To a stirred solution of 6-((6-((Biotinoyl)amino)hexanoyl)amino)hexanoic acid, succinimidyl ester (biotin-NHS ester) (0.2 g, 0.35 mmol) in dry DMF (5 ml), propargyl amine (0.04 ml, 0.6 mmol) was added. A white precipitate formed within 15 min and the mixture was stirred overnight. The solvent was removed in vacuo and the compound was dissolved in CHCl3. Next the CHCl3 was slowly added to a stirred solution of hexane, forming a white precipitate, which on drying afforded 0.15 g (83%). Mass Spect. (FAB) MW 508 [M+]; NMR assigned. Crisp, G. T.; Gore, J. Syn. Comm. 1997, 27, 2203-2125
