To a solution of Intermediate A (75 mg, 0.458 mmol) in DMF (2 mL) was added NaH (60% in oil, 50 mg, 1.25 mmol) and the mixture stirred at RT for 20 min, before Intermediate 59b (75 mg, 0.416 mmol) was added. This mixture was stirred at 60° C. for 1 h. The reaction mixture was applied to an SCX-2 cartridge (10 g) and washed with MeOH. The product was eluted with 2M NH3 in MeOH; concentration in vacuo gave a residue. FCC, using 0-10% [2M NH3 in MeOH] in DCM gave the title compound as a yellow gum (82 mg, 61%). LCMS (Method 4): Rt 1.49 min, m/z 324 [MH+].
