Reaction Steps

In a flame dried round-bottomed flask equipped with a magnetic stir bar and under inert atmosphere (N2), a mixture of 2-[5-(1,1-difluoro-ethyl)-furan-2-ylmethyl]-4-nitro-2H-[1,2,3]triazole (471 mg, 1.82 mmol), iron powder (309 mg, 5.47 mmol) and NH4Cl (493 mg, 9.12 mmol) in a mixture of EtOH (7.0 mL) and water (3.5 mL) was stirred at 85° C. for 20 min. The reaction mixture was filtered while hot and concentrated under reduced pressure. CH2Cl2 (10 mL) was added followed by water (10 mL). The aq. layer was extracted with CH2Cl2 (2×10 mL) and the combined org. extracts were dried over MgSO4, filtered, and the solvents were removed under reduced pressure to give the title compound as a yellow oil. LC-MS-conditions 02: tR=0.82 min; [M+H+AcCN]+=270.24.
