Reaction Steps

A solution of Intermediate 76a (214 mg, 0.27 mmol) and DIPEA (95 μL, 0.54 mmol) in THF (5 mL) was treated with morpholine (47 μL, 0.54 mmol). The mixture was stirred at 50° C. for 18 h in a sealed vial. The volatiles were concentrated in vacuo and the product was purified by MDAP purification (Method 7) to give the title compound (72 mg, 34%). LCMS (Method 5): Rt 3.60 min, m/z 782.6 [MH+].+]. 1H NMR (400 MHz, d6-DMSO): 1.28 (9H, s), 1.57-1.65 (2H, m), 1.68-1.77 (4H, m), 1.80-1.94 (4H, m), 1.99-2.17 (2H, m), 2.24-2.32 (3H, bs), 2.36-2.42 (2H, t, J=6.9), 3.11-3.17 (4H, m), 3.48-3.52 (4H, m), 4.09-4-15 (2H, t, J=6.52 Hz), 4.76-4.84 (1H, m), 5.54 (1H, t, J=4.3 Hz), 6.34 (1H, s), 7.03-7.11 (2H, m), 7.16 (1H, dd, J=2.0, 9.9 Hz), 7.21-7.41 (5H, m), 7.54 (1H, d, J=8.5 Hz), 7.59-7.65 (2H, m), 8.14 (1H, br s).
