A solution of Intermediate 78e (44 mg, 0.057 mmol) and dimethylamine (2M in THF, 0.57 mL, 1.14 mmol) in THF (1 mL) was heated at 60° C. for 18 h. The reaction mixture was cooled to RT and the solvent was removed under a stream of air, to leave a residue which was purified by MDAP (Method 7), to afford the title compound (16 mg, 38%). LCMS (Method 5): Rt: 3.42 min, m/z 726.5 [MH+]. 1H NMR (400 MHz, d6-DMSO): 1.10 (3H, d, J=6.2 Hz), 1.28 (9H, s), 1.54-1.65 (1H, m), 1.78-1.95 (3H, m), 1.95-2.08 (2H, m), 2.08-2.19 (2H, m), 2.21 (6H, s), 2.65 (2H, t, J=5.6 Hz), 3.09-3.16 (1H, m, obscured by water), 3.80-3.89 (1H, m), 4.06-4.14 (1H, m), 4.16 (2H, t, J=5.6 Hz), 4.75-4.84 (1H, m), 5.52 (1H, t, J=4.0 Hz), 6.34 (1H, s), 7.04-7.13 (3H, m), 7.22-7.39 (5H, m), 7.52-7.58 (2H, m), 7.79 (1H, d, J=1.9 Hz), 8.15-8.19 (2.2H, m).
