A solution of Intermediate 154a (50.5 mg, 0.066 mmol) and N-methyl homopiperazine (39 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 a white solid of the title compound (28 mg, 54%). LCMS (Method 5): Rt 3.28 min, m/z 775 [MH+]. 1H NMR (400 MHz, d6-DMSO): 0.91 (3H, d, J=6.0 Hz), 1.27 (9H, s), 1.47-1.56 (2H, m), 1.62-1.73 (4H, m), 1.75-2.18 (6H, m), 2.28 (3H, s), 2.56-2.63 (4H, m), 2.70-2.77 (4H, m), 2.85 (2H, t, J=6.0 Hz), 2.87-2.95 (1H, m), 3.12-3.20 (1H, m), 3.27-3.35 (1H, m), 4.07 (2H, t, J=5.6 Hz), 4.77-4.86 (1H, m), 5.52 (1H, t, J=3.8 Hz), 6.32 (1H, s), 6.93-6.98 (1H, m), 7.04-7.10 (2H, m), 7.14 (1H, d, J=8.9 Hz), 7.19 (1H, dd, J=9.8 Hz, 2.2 Hz), 7.24-7.42 (5H, m), 7.64 (1H, d, J=4.9 Hz), 7.69 (1H, d, J=1.8 Hz), 8.18 (1H, s), 8.20 (2H, s).
