Procedure

A brown solution of Intermediate 29c (177 mg, 0.420 mmol), Intermediate 81d (151 mg, 0.400 mmol) and DIPEA (0.087 mL, 0.50 mmol) in dry dioxane (5 mL) was stirred at 100° C. for 3 h. The cooled solution was concentrated in vacuo, suspended in water (10 mL) and extracted with DCM (2×10 mL). The combined organics were passed through a hydrophobic frit and concentrated under vacuum to leave a dark brown gum. FCC, using 3-8% MeOH in DCM, gave the title compound as an orange solid (188 mg, 72%). LCMS (Method 4): Rt 3.63 min, m/z 649 [MH+].
