実験手順

A solution of Intermediate 53b (238 mg, 0.41 mmol), Intermediate 78b (220 mg, 0.61 mmol) and DIPEA (158 μL, 0.91 mmol) in dioxane (2.5 mL) was heated at 60° C. for 18 h. The reaction mixture was cooled and diluted with DCM (5 mL). The organic layer was washed with water (2×5 mL), passed through a phase separator and concentrated in vacuo. The residue was purified by FCC, using 0-10% [2M NH3 in MeOH] in DCM, to afford the title compound (62 mg, 19%). LCMS (Method 3): Rt: 4.00 min, m/z 783/785 [MH+].
