실험 절차

In an argon-purged 100 ml flask, biotin-N-hydroxy-succinimide (251 mg, 0.735 mmol; Compound 1, Sigma-Aldrich) was dissolved in 26.7 ml dry DMF and mixed with allylamine (50 μl, 0.668 mmol; Nacalai Tesque, Inc., Japan), followed by stirring at room temperature with the flask covered with aluminum foil for light shielding. The progress of the reaction was monitored by C18 reversed-phase HPLC (HPLC conditions; column: μ-Bondsphere φ19×150 mm (Waters); mobile phase: 20% acetonitrile in H2O; elution speed: 10 ml/min; detection: UV absorption (200 nm)). At 3 hours after initiation of the reaction, it was confirmed that the source material biotin-N-hydroxysuccinimide was almost completely converted into Compound 2. This reaction solution was used directly in the subsequent reaction.
