Procedure

To a solution of Intermediate 106b (0.25 mmol) in THF (2.5 mL) was added DIPEA (130 μL, 0.75 mmol) followed by N-methylpiperazine (83 μL, 0.75 mmol). The reaction mixture was heated at 50° C. for 18 h in a sealed tube, then cooled and 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 resultant residue was purified by FCC on silica, using a gradient of 0-10% [2M NH3 in MeOH] in DCM followed by HPLC (C18 X-select column, 10-98% gradient MeCN in H2O, 0.1% HCO2H), to give the title compound (13 mg, 7%). LCMS (Method 5): Rt 3.44 min, m/z 717 [MH+]. 1H NMR (400 MHz, d6-DMSO): 1.27 (9H, s), 1.57-1.66 (2H, m), 1.68-1.77 (4H, m), 1.79-1.95 (2H, m), 1.98-2.19 (5H, m), 2.22-2.46 (8H, m), 3.14 (4H, t, J=5.3 Hz), 3.49 (2H, s), 4.76-4.85 (1H, m), 5.54 (1H, t, J=4.4 Hz), 6.33 (1H, s), 7.09 (1H, d, J=8.6 Hz), 7.17 (1H, dd, J=9.8, 2.2 Hz), 7.25-7.47 (8H, m), 7.59-7.65 (2H, m), 8.11 (1H, s).
