Procedure
To a solution of Intermediate 130b (0.25 mmol) in THF (2.5 mL) was added N-methylpiperazine (277 μL, 2.50 mmol) and the reaction stirred at 50° C. for 24 h. After cooling, the mixture was partitioned between EtOAc and water. The aqueous phase was extracted with EtOAc (×3) and the combined organic layers were washed with brine, dried (MgSO4) and concentrated in vacuo. The resulting residue was purified by FCC on silica, using a gradient of 0-10% [2M NH3 in MeOH] in DCM, followed by MDAP (Method 7) purification, to give the title compound (37 mg, 19%). LCMS (Method 5): Rt 3.77 min, m/z 745 [MH+]. 1H NMR (400 MHz, d6-DMSO): 0.55 (3H, d, J=6.2 Hz), 0.58 (3H, d, J=6.2 Hz), 1.23 (9H, s), 1.35-1.54 (3H, m), 1.63-1.68 (2H, m), 1.72-1.86 (2H, m), 1.86-1.92 (1H, m), 2.01-2.06 (2H, m), 2.07 (3H, s), 2.26 (4H, br s), 2.34 (4H, br s), 3.08-3.20 (2H, m), 3.46 (2H, s), 4.78 (1H, td, J=8.6, 5.9 Hz), 5.47 (1H, t, J=4.2 Hz), 6.28 (1H, s), 7.00 (1H, d, J=8.6 Hz), 7.15 (1H, dd, J=9.8, 2.1 Hz), 7.18-7.25 (2H, m), 7.25-7.31 (3H, m), 7.32-7.37 (2H, m), 7.41 (1H, t, J=7.6 Hz), 7.61 (1H, d, J=9.7 Hz), 7.83 (1H, d, J=1.8 Hz), 8.05 (1H, s), 8.12 (1.1H, s).
