Versuchsvorschrift

To a stirring solution of #128 (1.67 g, 3.1 mmol, 1.0 eq.) in 20 of dichloromethane and 2 mL of DMF, #121 (2.4 g, 3.1 mmol, 1.0 eq.) was added followed by HATU (1.29 g, 3.39 mmol, 1.1 eq.) and then Hunig's base (2.2 mL, 12.3 mmol, 4.0 eq.). The reaction was allowed to stir at room temperature for -2 hours. Reaction was reduced down, diluted with ethyl acetate before being washed with 0.5 N HCl and brine. Organics where dried over sodium sulfate and then reduced down onto silica. Residue was purified by Silica Chromatography (Gradient: 0%-50% acetone in heptanes) producing #129 (1.9 g, 62%) as a white solid. LC-MS (Protocol Q): m/z 996.3 [M+H+] retention time=2.53 minutes.
