Reaction Steps

To a suspension of NaH (60% in mineral oil, 107 mg, 2.68 mmol) in DMF (2.00 mL) was added Intermediate A (110 mg, 0.67 mmol) and the reaction stirred for 20 min. Intermediate 61b (150 mg, 0.67 mmol) was added in DMF (2.00 mL) and the reaction heated to 60° C. for 1 h. The reaction was cooled and 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 (72.0 mg, 28%). LCMS (Method 4): Rt 0.29 min, m/z 378.2 [MH+].
