Procedure

To a solution of Intermediate A (225 mg, 1.38 mmol) in DMF (3 mL) was added NaH (60% in oil, 150 mg, 3.75 mmol) and the mixture stirred at RT for 20 min, before Intermediate 45c (350 mg, 1.25 mmol) was added. This mixture was stirred at 60° C. for 7 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 0-20% [2M NH3 in MeOH] in DCM, gave the title compound as an orange oil (270 mg, 51%). LCMS (Method 4): Rt 0.22 min, m/z 423 [MH+].
