実験手順
A yellow solution of Intermediate 127a (0.100 mmol) and dimethylamine (2M in THF, 1.0 mL, 2.0 mmol) in THF (1 mL) was stirred in a sealed vial at 60° C. for 16 h. The cooled solution was concentrated in vacuo, redissolved in MeOH (2 mL), applied to an SCX-2 cartridge (5 g) and washed with MeOH (15 mL). The product was eluted with 2M NH3 in MeOH (15 mL); concentration in vacuo left a yellow film. MDAP (Method 7) gave the title compound as an off-white solid (42 mg, 62%). LCMS (Method 5): Rt 3.43 min, m/z 614.4 [MH+]. 1H NMR (400 MHz, d6-DMSO): 0.91 (3H, d, J=6.3 Hz), 1.21 (9H, s), 1.46-1.56 (2H, m), 1.63-1.72 (2H, m), 1.76-1.85 (2H, m), 1.92-2.01 (2H, m), 2.03-2.11 (1H, m), 2.15-2.19 (1H, m), 2.21 (6H, s), 2.61 (2H, t, J=6.9 Hz), 2.91 (1H, ddd, J=12.2, 9.2, 4.0 Hz), 3.17 (1H, dt, J=12.2, 4.3 Hz), 3.28-3.36 (1H, m), 3.99 (2H, t, J=6.9 Hz), 4.87 (1H, td, J=8.5, 6.2 Hz), 5.53 (1H, t, J=4.1 Hz), 6.03 (1H, s), 6.97 (1H, d, J=8.7 Hz), 7.21 (1H, dd, J=9.8, 2.2 Hz), 7.29 (1H, td, J=7.3, 2.0 Hz), 7.34-7.41 (3H, m), 7.65 (1H, dd, J=9.8, 0.8 Hz), 7.71 (1H, d, J=2.1 Hz), 8.17 (1.4H, s), 8.48 (1H, s).
