Procedure

To a solution of Intermediate 167b (0.16 mmol) in THF (2.5 mL) was added dimethylamine solution (2M THF, 1.6 mL, 3.27 mmol) and the reaction stirred at 50° C. for 24 h in a sealed vessel. The crude reaction mixture was 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 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 (20 mg, 16%). LCMS (Method 5): Rt 3.58 min, m/z 676 [MH+]. 1H NMR (400 MHz, d6-DMSO): 0.86 (3H, d, J=6.2 Hz), 1.23 (9H, s), 1.42-1.50 (2H, m), 1.58-1.67 (2H, m), 1.70-1.90 (4H, m), 1.94-2.03 (1H, m), 2.04-2.12 (2H, m), 2.11 (6H, s), 2.86 (1H, ddd, J=12.7, 9.0, 3.9 Hz), 3.12 (1H, dt, J=11.9, 4.1 Hz), 3.39 (2H, s), 4.77 (1H, td, J=8.4, 5.7 Hz), 5.46 (1H, t, J=4.2 Hz), 6.27 (1H, s), 7.02 (1H, d, J=8.6 Hz), 7.15 (1H, dd, J=9.8, 2.1 Hz), 7.20-7.29 (4H, m), 7.29-7.34 (1H, m), 7.35-7.41 (3H, m), 7.59 (1H, d, J=10.0 Hz), 7.64 (1H, d, J=1.8 Hz), 8.07 (1H, s), 8.25 (0.3H, s).
