A solution of Intermediate 154a (50.5 mg, 66 μmol) and 8-aza-bicyclo[3.2.1]octane (38 mg, 0.34 mmol) in THF (1 mL) was heated at 60° C. overnight in a sealed vessel. The reaction mixture was concentrated in vacuo and the residue purified by MDAP (Method 7) to give the title compound as a white solid (32 mg, 62%). LCMS (Method 5): Rt 3.84 min, m/z 772 [MH+]. 1H NMR (400 MHz, d6-DMSO): 0.91 (3H, d, J=6.4 Hz), 1.21-1.36 (11H, m), 1.37-1.54 (4H, m), 1.58-1.72 (4H, m), 1.74-2.18 (8H, m), 2.72 (2H, d, J=6.4 Hz), 2.86-2.95 (1H, m), 3.11-3.20 (1H, m), 3.22-3.36 (5H, m), 4.09 (2H, t, J=6.1 Hz), 4.77-4.86 (1H, m), 5.52 (1H, t, J=4.1 Hz), 6.33 (1H, s), 6.94-6.99 (1H, m), 7.04-7.11 (2H, m), 7.14 (1H, d, J=8.6 Hz), 7.18 (1H, dd, J=10.2 Hz, 2.1 Hz), 7.24-7.42 (5H, m), 7.64 (1H, d, J=10.2 Hz), 7.69 (1H, d, J=2.0 Hz), 8.17 (1H, s), 8.19 (1.6H, s).
