Procedure

To a solution of Intermediate A (179 mg, 1.10 mmol) in DMF (3 mL) was added NaH (60% dispersion in oil, 120 mg, 3.00 mmol) and the mixture stirred at RT for 25 min. A solution of Intermediate 92b (958 mg, 1.10 mmol) in DMF (3 mL) was added and the mixture stirred at 60° C. for 1.5 h. The solution was cooled, water added, and the mixture extracted with DCM (4×25 mL). The combined organics were dried and concentrated in vacuo. The residue was purified by FCC, using 0-16% MeOH in DCM, to give the title compound as a brown gum (216 mg, 37%). LCMS (Method 3): Rt 3.08 min, m/z 536 [MH+].
