Reaction Steps

A solution of Intermediate 131d (44.5 mg, 0.06 mmol) and pyrrolidine (24.8 μL, 0.30 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 (15 mg, 35%). LCMS (Method 5): Rt 3.70 min, ink 716.6 [MH+]. 1H NMR (400 MHz, d6-DMSO): 0.91 (3H, d, J=6.6 Hz), 1.28 (9H, s), 1.50 (2H, m), 1.61-1.72 (6H, m), 1.76-2.18 (6H, overlapped m), 2.53 (m, obscured by solvent), 2.72 (2H, m), 2.82 (2H, m), 2.90 (1H, m), 3.16 (1H, m, obscured by solvent), 3.31 (m, obscured by solvent), 4.82 (1H, m), 5.52 (1H, t, J=4.2 Hz), 6.33 (1H, s), 7.10 (1H, d, J=8.4 Hz), 7.19 (1H, dd, J=10.0, 2.0 Hz), 7.24-7.44 (8H, m), 7.64 (1H, m), 7.69 (1H, m), 8.14 (1H, s), 8.19 (1H, s).
