Reaction Conditions

Reaction Steps

To a solution of Intermediate 119f (0.10 mmol) in THF (2 mL) was added dimethylamine (2M in MeOH, 0.4 mL, 0.8 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 HPLC (XBridge C18 column, 30-98% MeCN in H2O, 0.1% NH4OH), to give the title compound (12 mg, 18%). LCMS (Method 5): Rt 3.43 min, m/z 666 [MH+]. 1H NMR (400 MHz, d6-DMSO): 1.21 (9H, s), 1.54-1.60 (2H, m), 1.65-1.71 (4H, m), 1.86-1.94 (2H, m), 1.95-2.05 (1H, m) 2.13 (6H, s), 2.13-2.16 (1H, m), 2.55 (2H, t, J=6.3 Hz), 3.10 (4H, t, J=5.2 Hz), 4.05 (2H, t, J=7.1 Hz), 4.86 (1H, td, J=8.4, 5.5 Hz), 5.51 (1H, t, J=4.5 Hz), 6.32 (1H, s), 7.12 (1H, dd, J=10.0, 1.9 Hz), 7.20-7.25 (2H, m), 7.28-7.36 (3H, m), 7.56-7.59 (2H, m), 7.63 (1H, d, J=1.4 Hz), 7.90 (1H, d, J=8.6 Hz), 9.63 (1H, br s).
