Procedure

To a solution of Intermediate 130b (0.32 mmol) in THF (3.0 mL) was added pyrrolidine (530 μL, 6.4 mmol) and the reaction stirred at 50° C. for 24 h. After cooling, the 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 (60 mg, 24%). LCMS (Method 5): Rt 3.79 min, ink 716 [MH+]. 1H NMR (400 MHz, d6-DMSO): 0.55 (3H, d, J=6.2 Hz), 0.58 (3H, d, J=6.2 Hz), 1.23 (9H, s), 1.35-1.54 (3H, m), 1.60-1.68 (6H, m), 1.72-1.85 (2H, m), 1.86-1.92 (1H, m), 2.01-2.06 (2H, m), 2.38-2.44 (4H, m), 3.08-3.20 (2H, m), 3.58 (2H, s), 4.77 (1H, td, J=8.6, 5.9 Hz), 5.48 (1H, t, J=4.2 Hz), 6.28 (1H, s), 7.00 (1H, d, J=8.6 Hz), 7.15 (1H, dd, J=9.8, 2.1 Hz), 7.18-7.25 (2H, m), 7.26-7.35 (4H, m), 7.37 (1H, s), 7.41 (1H, t, J=7.6 Hz), 7.61 (1H, d, J=9.7 Hz), 7.83 (1H, d, J=1.8 Hz), 8.05 (1H, s), 8.13 (1.2H, s).
