Reaction Steps

A brown solution of Intermediate 148g (0.099 mmol) and dimethylamine (2M in THF, 0.99 mL, 1.98 mmol) in THF (1 mL) was stirred in a sealed vial at 60° C. for 16 h. The solution was decanted and concentrated. MDAP (Method 7) gave the title compound as a pale yellow solid (50 mg, 65%). LCMS (Method 5): Rt 3.62 min, m/z 718.6 [MH+]. 1H NMR (400 MHz, d6-DMSO): 0.42-0.53 (4H, m), 1.27 (9H, s), 1.53-1.61 (2H, m), 1.74-1.96 (6H, m), 1.99-2.15 (2H, m), 2.20 (6H, s), 2.63 (2H, t, J=5.8 Hz), 3.22-3.29 (2H, m), 4.09 (2H, t, J=5.8 Hz), 4.81 (1H, td, J=8.6, 5.5 Hz), 5.48 (1H, t, J=4.3 Hz), 6.33 (1H, s), 6.95-6.98 (1H, m), 7.06-7.12 (3H, m), 7.14 (1H, dd, J=9.9, 2.2 Hz), 7.25-7.42 (5H, m), 7.56 (1H, d, J=2.1 Hz), 7.61 (1H, dd, J=9.8, 0.8 Hz), 8.12 (1H, s), 8.17 (1.4H, s).
