    • 3 (1 g, 20.4 mmol) was dissolved in dry DMF (50 ml) and applied to triethylammonium Dowex gel (40 ml) in a glass chromatography column. The column eluant was collected directly into a flask (50 ml) containing 3 (60 mg, 0.058 mmol) previously dried under vacuum from methanol solution. After 16h at 65°C in the dark, azide exchange was judged to be complete and solvent with impurities was removed by SOURCE 15Q column that was eluted with a 0-50% gradient of 2 M TEAB (6 ml/min). Fractions containing the azido affinity probe 2 were combined and freeze-dried, after which the probe was stored in aqueous solution at -20°C.
