Versuchsvorschrift

The product from Example 4 Step C (235 mg) was combined with Boc-ethylenediamine (74 μL) and triethylamine (178 μL) in 3 mL of dichloromethane and stirred at room temperature for 1 hour. The reaction was diluted with EtOAc and washed with saturated NaHCO3 and brine, dried over Na2SO4 and concentrated in vacuo. The crude product was purified by flash chromatography on silica gel using EtOAc/hexane as mobile phase to give the titled compound. ESI+ MS: 678 [M+H]+.
