実験手順

Amine 41 (Example 24, 10 mg, 0.023 mmol) and N-(+)-biotinyl-6-aminocaproic acid succinimidyl ester (50, 10 mg, 0.023 mmol) are dissolved in 650 μL DMF with 5 μL TEA and left at room temperature over night. The product is purified by reverse phase MPLC by using a linear gradient from water to acetonitrile (0.08% TFA) to yield 15.1 mg (0.019 mmol, 86%) of the title compound. MS (ESI) m/z 763.0 [M+H]+.
