実験手順

To a stirring mixture of dimer acid #5 (12.1 g, 23.0 mM) and #67 (11.5 g, 23.0 mM) in 75 mL of dichloromethane under nitrogen, HATU (10.8 g, 27.6 mM) was added followed by Hunig's base (12.1 mL, 69.0 mM). The reaction was allowed to stir at room temperature for 15 hours. Reaction was concentrated to a smaller volume, taken up with ethyl acetate and washed with 1 N HCl two times. The organic layer was then washed with brine, dried over sodium sulfate, filtered, and concentrated in vacuo. Residue was then purified by silica gel chromatography (Gradient: 0% to 70% acetone in heptanes), producing #113 (12.3 g, 62%) as a white solid. LC-MS (Protocol Q): m/z 855.3 [M+H+], 877.2 [M+Na+], retention time=2.32 minutes; HPLC (Protocol R): /z 855.5 [M+H+], retention time=9.596 minutes (purity >97%).
