Procedure

Intermediate A (300 mg, 1.84 mmol) was added to an ice cold stirred suspension of sodium hydride (60% in mineral oil, 221 mg, 5.52 mmol) in DMF (15 mL) and stirred for 15 min. 2-Cyano-5-fluoropyridine (224 mg, 1.84 mmol) was added and the reaction warmed to RT. After 90 min, the reaction was quenched by dropwise addition of water and the mixture partitioned between EtOAc (75 mL) and water (150 mL). The aqueous layer was then extracted with EtOAc (3×). The combined organic layers were washed with brine, dried (MgSO4), filtered and evaporated in vacuo. The residue was purified by FCC, using 0-5% [2M NH3 in MeOH] in DCM, to give the title compound (255 mg, 0.96 mmol, 52%). LCMS (Method 4): Rt 0.28, 1.73, m/z 266.1 [MH+].
