Reaction Steps

To a solution of Intermediate A (123 mg, 0.755 mmol) in DMF (4 mL) was added NaH (60% in oil, 82 mg, 2.06 mmol) and the mixture stirred at RT for 20 min, before Intermediate 38b (260 mg, 0.687 mmol) was added. This mixture was heated at 60° C. in the microwave for 3 h. The reaction mixture was applied to an SCX-2 cartridge (25 g) and washed with MeOH. The product was eluted with 2M NH3 in MeOH; concentration in vacuo gave a residue. FCC, using 0-7% [2M NH3 in MeOH] in DCM, gave the title compound as a viscous yellow oil (100 mg, 23%). LCMS (Method 1): Rt 2.90 min, m/z 522 [MH+].
