Procedure

To a solution of Intermediate 123a (108 mg, 0.159 mmol) and DIPEA (0.083 mL, 0.48 mmol) in DCM (4 mL) was added methanesulfonyl chloride (36.5 mg, 0.318 mmol) and the resulting yellow solution stirred at RT for 20 min. Water (2 mL) and sat. aq. NaHCO3 solution (2 mL) were added, then the aqueous extracted with DCM (4 mL). The combined organics were passed through a hydrophobic fit and concentrated in vacuo to leave a yellow solid. The solid was dissolved in THF (2 mL), then dimethylamine (2 M in THF, 1.6 mL, 3.2 mmol) added, and the mixture stirred at 60° C. in a sealed vial for 18 h. The cooled solution was concentrated in vacuo, redissolved in MeOH (1 mL), applied to an SCX-2 cartridge (5 g), washed with MeOH (20 mL) and eluted with 2 M NH3 in MeOH (20 mL); concentration in vacuo gave a glassy yellow solid (98 mg). MDAP (Method 7) gave a pale yellow solid (63 mg). Additional purification by HPLC (Gemini C18, 15-65% MeCN in water, 0.1% HCO2H, 20 min, ×2) gave the title compound as a white solid (18.6 mg, 17%). LCMS (Method 5): Rt 3.62 min, m/z 706.6 [MH+]. 1H NMR (400 MHz, d6-DMSO): 0.88 (3H, d, J=6.3 Hz), 1.28 (9H, s), 1.48-1.56 (2H, m), 1.65-1.71 (2H, m), 1.76-1.96 (4H, m), 2.00-2.14 (2H, m), 2.17 (6H, s), 2.59 (2H, t, J=5.8 Hz), 2.95 (1H, ddd, J=12.2, 8.1, 4.8 Hz), 3.18 (1H, dt, J=12.1, 4.3 Hz), 3.26-3.29 (1H, m), 4.07 (2H, t, J=5.8 Hz), 4.81 (1H, td, J=8.6, 5.6 Hz), 5.53 (1H, t, J=4.3 Hz), 6.31 (1H, s), 6.95 (1H, dd, J=8.4, 2.2 Hz), 7.09 (2H, m), 7.18 (1H, dd, J=9.8, 2.2 Hz), 7.25-7.41 (6H, m), 7.64 (1H, d, J=9.9 Hz), 7.70 (1H, d, J=2.1 Hz), 8.34 (1H, s), 8.50 (0.3H, s).
