Procedure

To a solution of Intermediate 141c (0.19 mmol) in THF (2.0 mL) was added dimethylamine (2M in MeOH, 1.9 mL, 3.8 mmol) and the reaction was heated to 50° C. in a sealed tube overnight. The crude reaction mixture was 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 (50 mg, 34%). LCMS (Method 5): Rt 3.33 min, m/z 708 [MH+]. 1H NMR (400 MHz, d6-DMSO): 0.83 (3H, d, J=5.7 Hz), 1.23 (9H, s), 1.78-1.92 (2H, m), 1.94-2.04 (1H, m), 2.04-2.12 (1H, m), 2.16 (6H, s), 2.59 (2H, t, J=5.7 Hz), 2.94 (1H, ddd, J=12.2, 7.3, 4.7 Hz), 3.16 (1H, dt, J=12.2, 3.3), 3.35-3.43 (2H, m), 3.72-3.80 (2H, m), 3.81-3.87 (1H, m), 4.04 (2H, t, J=5.7 Hz), 4.77 (1H, td, J=8.5, 5.9 Hz), 5.50 (1H, t, J=4.1 Hz), 6.28 (1H, s), 6.90-6.94 (1H, m), 7.01-7.09 (3H, m), 7.14-7.18 (1H, dd, J=9.8, 2.1 Hz), 7.20-7.26 (2H, m), 7.26-7.30 (1H, m), 7.30-7.38 (2H, m), 7.62 (1H, d, J=9.8 Hz), 7.78 (1H, d, J=1.8 Hz), 8.09 (1H, s), 8.12 (1.4H, s).
