Reaction Steps

To a solution of Intermediate 47b (150 mg, 0.64 mmol) and Intermediate A (126 mg, 0.64 mmol) in DMF (3 mL) was added NaH (60% in mineral oil, 90 mg, 2.24 mmol) portionwise. The mixture was stirred at 60° C. for 1.5 h then allowed to cool to RT. The mixture was carefully quenched by pouring into MeOH (10 mL), then applied to an SCX-2 cartridge 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 brown solid (180 mg, 75%). LCMS (Method 4): Rt 0.49, m/z 378 [MH+].
