Procedure

To a stirring mixture of #114 (240 mg, 0.379 mmol, 1.0 eq.), #152 (71 mg, 0.49 mmol, 1.3 eq.), and HATU (188 mg, 0.49 mmol, 1.3 eq.) in 10 mL of dichloromethane, Hunig's base (0.27 mL, 4.1 mM, 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 (36 mg, 1.5 mmol, 4 eq.) dissolved in 2 mL of water was added. Reaction was allowed to stir at room temperature for 1 hour. 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) #153 (220 mg, 78%) as a white solid. LC-MS (Protocol Q): m/z 744.8 [M+H+], retention time=1.16 minutes; HPLC (Protocol A at 45° C.): /z 744.4 [M+H+], retention time=6.713 minutes (purity >98%). 1H NMR (400 MHz, DMSO-d6), δ 9.72-9.85 (m), 8.65 (t), 8.41 (d), 8.14 (d), 7.14-7.28 (m), 4.69-4.79 (m), 4.38-4.53 (m), 3.95-4.04 (m), 3.73-3.79 (m), 3.37-3.62 (m), 3.13-3.33 (m), 2.95-3.10 (m), 2.79-2.89 (m), 2.67-2.75 (m), 2.00-2.46 (m), 1.61-1.90 (m), 1.22-1.54 (m), 1.02-1.09 (m), 0.95-1.01 (m), 0.85-0.94 (m), 0.75-0.83 (m)
