Versuchsvorschrift
A solution of 4 (16 mg, 0.015 mmol) and 5 (6.2 mg, 0.02 mmol) in DMF (2 mL) was treated with DIPEA (10 uL). The reaction mixture was stirred for 1 hr at 25° C. The final product was purified by Prep HPLC (SymmetrPrep C18, 7 μm, 19×150 mm column), eluted at 10 ml/min (0.01% TFA in water/acetonitrile) with a gradient: 10% acetonitrile in 5 min, 10% to 50% acetonitrile in 15 min, maintaining 50% acetonitrile in 5 min, 50% to 100% acetonitrile in 5 min, to obtain 6 (13 mg, 75%). MS: calcd for C51H55BrN10O9 (M+H) m/z 1031.33 found 1031.6.
