Versuchsvorschrift

To a solution of Intermediate 167b (0.19 mmol) in THF (2 mL) was added DIPEA (130 μL, 0.75 mmol) and N-(methoxyethyl)methylamine (81 μL, 0.75 mmol) and the reaction stirred at 50° C. for 24 h. 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 resultant 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, 14%). LCMS (Method 5): Rt 3.65 min, m/z 720 [MH+]. 1H NMR (400 MHz, d6-DMSO): 0.86 (3H, d, J=6.2 Hz), 1.23 (9H, s), 1.42-1.48 (2H, m), 1.58-1.67 (2H, m), 1.72-1.92 (4H, m), 1.96-2.12 (2H, m), 2.12 (3H, s), 2.49 (2H, t, J=6.0 Hz), 2.86 (1H, ddd, J=12.7, 9.0, 3.9 Hz), 3.12 (1H, dt, J=12.1, 4.3 Hz), 3.16 (3H, s), 3.39 (2H, t, J=6.0 Hz), 3.50 (2H, s), 4.77 (1H, td, J=8.4, 5.7 Hz), 5.47 (1H, t, J=4.2 Hz), 6.28 (1H, s), 7.02 (1H, d, J=8.6 Hz), 7.14 (1H, dd, J=9.8, 2.1 Hz), 7.20-7.25 (2H, m), 7.25-7.30 (2H, m), 7.30-7.35 (2H, m), 7.38 (1H, s), 7.40 (1H, t, J=7.7 Hz), 7.59 (1H, d, J=10.0 Hz), 7.64 (1H, d, J=1.8 Hz), 8.07 (1H, s), 8.28 (0.2H, s).
