Procedure

A mixture of Intermediate 5c (109 mg, 0.3 mmol) and Intermediate 35c (140 mg, 0.3 mmol) in 1,4-dioxane (3 mL) and DIPEA (78 μL, 0.45 mmol) was stirred at 90° C. for 4 h. The cooled mixture was concentrated in vacuo. The residue was purified by FCC, using 0-14% MeOH in DCM, to give the title compound as an off-white powder after freeze-drying (115 mg, 56%). LCMS (Method 5): Rt 3.47 min, m/z 681 [MH+]. 1H NMR (400 MHz, do-DMSO): 1.28 (9H, s), 1.83-2.26 (11H, m), 2.31-2.39 (1H, m), 3.04 (2H, t, J 6.8), 3.09 (1H, m), 3.59 (2H, q, J 6.0), 3.99 (1H, t, J 8.2), 4.78-4.86 (1H, m), 4.95 (1H, t, J 5.6), 5.36-5.41 (1H, m), 6.33 (1H, s), 7.08 (1H, d, J 8.4), 7.24-7.46 (9H, m), 7.75 (1H, d, J 9.6), 8.12 (1H, s), 8.25 (1H, br d).
