実験手順

To a suspension of NaH (60% in mineral oil, 51.0 mg, 1.27 mmol) in DMF (1.50 mL) was added Intermediate A (51.0 mg, 0.32 mmol) and the reaction stirred for 20 min. Intermediate 83c (75.0 mg, 0.32 mmol) was added in DMF (1.50 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 0-10% [2M NH3 in MeOH] in DCM, gave the title compound (31 mg, 26%). LCMS (Method 4): Rt 0.32, in/z 380.0 [MH+].
