Reaction Steps
To a solution of Intermediate A (122 mg, 0.75 mmol) in DMF (3 mL) was added NaH (60% dispersion in oil, 60 mg, 1.5 mmol) and the mixture stirred at RT for 25 min. A solution of Intermediate 66b (315 mg, 0.75 mmol) in DMF (2.5 mL) was added and the mixture stirred at 60° C. for 1.5 h. The cooled mixture was diluted with water and extracted with DCM (5×25 mL). The combined organics were dried and concentrated in vacuo. The residue was purified by FCC, using 0-14% [2M NH3 in MeOH] in DCM, to give the title compound as a dark brown gum (180 mg, 42%). LCMS (Method 3): Rt 3.35 min, m/z 564 [MH+].
