反応手順

Intermediate 1d (404 mg, 2.48 mmol) was added to a stirred solution of sodium hydride (60% in mineral oil, 298 mg, 7.44 mmol) in anhydrous DMF (15 mL) at RT under an argon atmosphere. The reaction mixture was stirred at RT for 15 min, then Intermediate 26c (0.70 g, 2.48 mmol) was added, and stirring at 60° C. was continued for 1 h. After cooling, the reaction mixture was quenched by careful addition of a saturated aqueous solution of NH4Cl and water (1:1) and extracted with EtOAc (×3). The combined organic layers were washed with a saturated aqueous solution of NaHCO3 followed by brine, dried and concentrated in vacuo. The resultant residue was purified by FCC, using 0-20% [2M NH3 in MeOH] in DCM to afford the title compound (345 mg, 33%) as a brown residue. LCMS (Method 3): Rt 2.34 min, m/z 425, 427. [MH+].
