Reaction Steps

Pyrrolidine (36 μL, 0.43 mmol) was added to a solution of Intermediate 96f (111 mg, 0.14 mmol) in THF (2 mL). The reaction was heated to 60° C. in a sealed vial overnight. The mixture was cooled, evaporated in vacuo and the residue was purified by FCC, using 0-15% MeOH in DCM, then triturated with Et2O to give the title compound (27 mg, 25%) as an off-white solid. LCMS (Method 5): Rt 3.87 min, m/z 746.6 [MH+]. 1H NMR (400 MHz, d6-DMSO): 0.55 (3H, d, J=6.0 Hz), 0.58 (3H, d, J 6.0 Hz), 1.23 (9H, s), 1.32-1.54 (3H, m), 1.53-1.78 (7H, m), 1.79-1.95 (2H, m), 1.96-2.10 (2H, m), 2.49-2.60 (2H, m), 2.68-2.94 (2H, m), 3.06-3.20 (3H, m), 3.27 (1H, m, obscured by water), 4.03-4.14 (2H, m), 4.74-4.83 (1H, m), 5.49 (1H, t, J=4.0 Hz), 6.29 (1H, s), 6.90-6.96 (1H, m), 7.01-7.09 (3H, m), 7.16 (1H, dd, J=9.7, 2.0 Hz), 7.19-7.25 (2H, m), 7.26-7.32 (2H, m), 7.33-7.39 (1H, m), 7.62 (1H, d, J=9.7 Hz), 7.84 (1H, m), 8.06 (1H, s).
