Conditions

Temperature: 90 °C

Procedure

A mixture of Intermediate 5c (150 mg, 0.410 mmol) and Intermediate 39b (230 mg, 0.430 mmol) in 1,4-dioxane (4 mL) and DIPEA (113 μL, 0.65 mmol) was stirred at 90° C. for 4.5 h. The mixture was concentrated in vacuo. The residue was purified by FCC twice, using 0-10% MeOH in DCM, to give the title compound as a pale yellow foam (234 mg, 76%). LCMS (Method 3): Rt 3.03 min, m/z 749.2 [MH+].
