Vorschrift

To a solution of Intermediate A (245 mg, 1.50 mmol) in DMF (4 mL) was added NaH (60% dispersion in oil, 180 mg, 4.50 mmol) and the mixture stirred at RT for 0.5 h. A solution of Intermediate 60a (330 mg, 1.50 mmol) in DMF (5 mL) was added and the mixture stirred at 60° C. for 2 h. The cooled solution was diluted with water and extracted with DCM (5×20 mL). The combined organics were dried and concentrated in vacuo. The residue was purified by FCC, using 0-15% [2M NH3 in MeOH] in DCM, to give the title compound as a brown solid after freeze-drying (408 mg, 74%). LCMS (Method 3): Rt 0.44 min, m/z 364 [MH+].
