Reaction Steps

To a solution of 4-[(5-nitro-2-pyridinyl)oxy]-3-(trifluoromethyl)benzonitrile (Reference Intermediate R13, 83 mg) in THF (3 mL)/water (1.5 mL) was added at room temperature, iron (75 mg, 1.34 mmol) and NH4Cl (72 mg, 1.34 mmol) and the resulting reaction mixture was stirred overnight. The mixture was filtered through a small pad of celite washing with EtOAc and water. To the filtered mixture was added an aqueous NaHCO3 saturated solution and the two phases were separated. The aqueous phase was extracted with EtOAc and the combined organic phases were dried and evaporated to dryness. The crude was purified by flash chromatography (companion system, 2×12 g Si cartridge, from 100:0 to 70:30 Cyclohexane/EtOAc) to afford the title compound (72 mg).
