Procedure

To a solution of Intermediate A (137 mg, 0.84 mmol) in DMF (3 mL) was added NaH (60% dispersion in oil, 68 mg, 1.7 mmol) and the mixture stirred at RT for 25 min. A solution of Intermediate 67a (197 mg, 0.84 mmol) in DMF (3 mL) was added and the mixture stirred at 60° C. for 1.25 h. The cooled mixture 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 0-14% [2M NH3 in MeOH] in DCM, to give the title compound as a dark brown gum (175 mg, 55%). LCMS (Method 3): Rt 2.22 min, m/z 378 [MH+].
