실험 절차

Intermediate A (115.4 mg, 0.71 mmol) was added to a mixture of NaH (60% in mineral oil, 87.2 mg, 2.18 mmol) in DMF (4 mL) at RT and stirred for 15 min. Intermediate 56d (237 mg, 0.54 mmol) was then added and the resulting mixture heated to 60° C. for 2 h. After cooling, the reaction was quenched with sat. aq. NH4Cl solution. The mixture was diluted with water and extracted with EtOAc. The combined organic extracts were washed with sat. aq. NaHCO3 solution and brine, and concentrated in vacuo. The resulting residue was loaded onto an SCX-2 cartridge, washed with MeOH then eluted with 1M NH3 in MeOH; concentration in vacuo gave the title compound as a brown residue (91 mg, 29%). LCMS (Method 3): Rt 3.08 min, m/z 579 [MH+].
