Reaction Steps

To a suspension of NaH (60% in mineral oil, 121 mg, 3.02 mmol) in DMF (2.00 mL) was added Intermediate A (122 mg, 0.75 mmol) and the reaction stirred for 20 min. Intermediate 84f (317 mg, 0.75 mmol) was added in DMF (2.00 mL) and the reaction heated to 60° C. for 1 h. The cooled reaction was quenched by dropwise addition of methanol, before being diluted with methanol and loaded onto an SCX-2 cartridge, which was washed with MeOH. The product was eluted with 2M NH3 in MeOH; concentration in vacuo gave a residue. FCC, using 2-10% [2M NH3 in MeOH] in DCM, gave the title compound (140 mg, 33%). LCMS (Method 4): Rt 2.37, m/z 564.2 [MH+].
