実験手順

Dbf-BAE (0.022 mmol), prepared above (F246), and EEDQ (0.024 mmol) are dissolved in NMP (0.3 mL). After 2 h of stirring at ambient temperature, N-glycylfluoresceinamine (0.022 mmol) and DIEA (0.012 mL, 0.067 mmol) are added as in examples 17 and 19 above. After about 18 h at ambient temperature, protected from light, the solvent is removed under reduced pressure and the residue purified by preparative TLC (reversed phase C18, 1 mm, methanol/500 mM NaCl, 6:4) giving the tracer shown below. ##STR15## D.
