Versuchsvorschrift

To a stirring mixture of #114 (125 mg, 0.198 mmol, 1.0 eq), #150 (37 mg, 0.26 mmol, 1.3 eq.), and HATU (98 mg, 0.26 mmol, 1.3 eq.) in 5 mL of dichloromethane, Hunig's base (0.14 mL, 0.80 mmol, 4.1 eq.) was added. The reaction was allowed to stir at room temperature for 1 hour. Reaction was concentrated in vacuo. THF (6 mL) was added to crude material. To this stirring mixture LiOH (14 mg, 0.59 mmol, 3.0 eq) dissolved in 2 mL of water was added. Reaction was allowed to stir at room temperature for 90 minutes. Reaction was concentrated in vacuo and residue was purified by medium pressure reverse phase C18 chromatography (Gradient: 5% to 40% acetonitrile in water with 0.02% TFA in each phase) #151 (147 mg, 69%) as a white solid. LC-MS (Protocol Q): m/z 744.3 [M+H+], retention time=1.19 minutes; HPLC (Protocol A at 45° C.): m/z 744.4 [M+H+], retention time=6.631 minutes (purity >98%). 1H NMR (400 MHz, DMSO-d6), δ 9.57-9.71 (m), 8.75 (d), 8.42 (d), 8.15 (d), 7.14-7.29 (m), 4.70-4.79 (m), 4.40-4.68 (m), 3.95-4.03 (m), 3.73-3.80 (m), 3.37-3.61 (m), 2.97-3.31 (m), 2.79-2.88 (m), 2.66-2.76 (m), 2.54-2.58 (m), 2.31-2.43 (m), 1.94-2.29 (m), 1.57-1.91 (m), 1.21-1.52 (m), 0.85-1.10 (m), 0.74-0.82 (m)
