Procedure

To a solution of Intermediate 124c (0.13 mmol) in THF (2.5 mL) was added dimethylamine (2M in MeOH, 1.3 mL, 2.6 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 2-10% [2M NH3 in MeOH] in DCM, followed by MDAP (Method 7) purification, to give the title compound (26 mg, 29%). LCMS (Method 5): Rt 3.68 min, m/z 694 [MH+]. 1H NMR (400 MHz, d6-DMSO): 0.55 (3H, d, J=6.2 Hz), 0.58 (3H, d, J=6.2 Hz), 1.20 (9H, s), 1.34-1.54 3H, m), 1.63-1.68 (2H, m), 1.72-1.86 (2H, m), 1.89-1.97 (1H, m), 2.01-2.07 (2H, m), 2.23 (6H, br s), 2.77 (2H, br s), 3.08-3.18 (2H, m), 4.22 (2H, br s), 4.80 (1H, dt, J=8.6, 5.6 Hz), 5.49 (1H, t, J=4.3 Hz), 6.22 (1H, s), 7.11 (1H, d, J=8.6 Hz), 7.16 (1H, dd, J=9.8, 2.2 Hz), 7.19-7.25 (1H, m), 7.28-7.33 (3H, m), 7.60 (1H, s), 7.62 (1H, d, J=9.6 Hz), 7.84 (1H, d, J=1.9 Hz), 7.98 (1H, s), 8.02 (1H, s).
