反応手順

A solution of Intermediate 154a (50.5 mg, 0.067 mmol) and pyrrolidine (27 μL, 0.33 mmol) in THF (1 mL) was stirred at 60° C. for 20 h in a sealed tube. The mixture was concentrated in vacuo and the residue purified by MDAP (Method 7). The title product was isolated as an off-white solid (29 mg, 59%). LCMS (Method 5): Rt 3.72 min, m/z 732.6 [MH+]. 1H NMR (400 MHz, d6-DMSO): 0.91 (3H, d, J=8.0 Hz), 1.28 (9H, s), 1.46-1.56 (2H, m), 1.61-1.72 (6H, m), 1.75-1.98 (4H, m), 1.99-2.18 (2H, m), 2.52 (4H, m, obscured by solvent), 2.80 (2H, t, J=8.0 Hz), 2.86-2.95 (1H, m), 3.12-3.19 (1H, m, obscured by water), 3.27-3.35 (1H, m, obscured by water), 4.11 (2H, t, J=8.0 Hz), 4.78-4.86 (1H, m), 5.52 (1H, t, J=4.0 Hz), 6.33 (1H, s), 6.97 (1H, dd, J=8.0 Hz, 4.0 Hz), 7.05-7.14 (3H, m), 7.19 (1H, dd, J=8.0 Hz, 4.0 Hz), 7.24-7.42 (5H, m), 7.64 (1H, d, J=8.0 Hz), 7.69 (1H, d, J=4.0 Hz), 8.14 (1H, s), 8.18 (1.3H, s).
