Reaction Steps

To a solution of Intermediate A (170 mg, 1.03 mmol) in DMF (4 mL) was added NaH (60% in oil, 103 mg, 2.59 mmol) and the mixture stirred at RT for 20 min, before Intermediate 85i (350 mg, 0.862 mmol) was added. This mixture was stirred at 60° C. for 4 h. The cooled mixture was diluted with EtOAc, washed with water (3×), brine, dried (MgSO4) and concentrated in vacuo. The residue was purified by FCC, using 0-10% [2M NH3 in MeOH] in DCM, to give the title compound as a clear viscous oil (230 mg, 48%). LCMS (Method 1): Rt 2.28 min, m/z 550 [MH+].
