Reaction Steps

Sodium hydride (60% in mineral oil, 840 mg, 21.9 mmol) was added portionwise to a stirred solution of Intermediate 1d (1.19 g, 7.31 mmol) in anhydrous DMF (30 mL) at RT under an argon atmosphere. Intermediate 31b (1.81 g, 7.31 mmol) was then added, and stirring at 60° C. was continued for 1.5 h. After cooling, the reaction mixture was quenched by careful addition of a saturated aqueous solution of NH4Cl and extracted with EtOAc (×2). The combined organic layers were washed with brine, dried (MgSO4) and concentrated in vacuo. The resultant residue was purified by FCC, using 0-10% MeOH in DCM to afford the title compound (1.48 g, 52%) as a brown foam. LCMS (Method 3): Rt 0.42 and 2.33 min, m/z 391. [MH+].
