Versuchsvorschrift

A yellow solution of Intermediate 127a (0.100 mmol) and piperidine (0.049 mL, 0.50 mmol) in dry DMF (2 mL) was stirred at 75° C. for 2.5 h. The cooled solution was concentrated in vacuo, redissolved in MeOH (2 mL), applied to an SCX-2 cartridge (2 g) and washed with MeOH (20 mL). The product was eluted with 2M NH3 in MeOH (15 mL); concentration in vacuo left a yellow solid. MDAP (Method 7) gave the title compound as an off-white solid (37 mg, 52%). LCMS (Method 5): Rt 3.68 min, m/z 654.5 [MH+]. 1H NMR (400 MHz, d6-DMSO): 0.91 (3H, d, J=6.3 Hz), 1.20 (9H, s), 1.33-1.38 (2H, m), 1.45-1.55 (6H, m), 1.63-1.72 (2H, m), 1.75-1.86 (2H, m), 1.89-2.02 (2H, m), 2.04-2.12 (1H, m), 2.14-2.21 (1H, m), 2.40 (4H, t, J=4.7 Hz), 2.61 (2H, t, J=7.1 Hz), 2.91 (1H, ddd, J=12.2, 9.2, 4.2 Hz), 3.16 (1H, dt, J=12.0, 4.3 Hz), 3.32 (1H, m), 3.99 (2H, t, J=7.1 Hz), 4.87 (1H, td, J=8.5, 5.7 Hz), 5.54 (1H, t, J=4.3 Hz), 6.04 (1H, s), 6.95 (1H, d, J=8.6 Hz), 7.22 (1H, dd, J=9.8, 2.2 Hz), 7.29 (1H, td, J=7.2, 1.8 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), 8.16 (1.4H, s), 8.29 (1H, s).
