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-(methoxymethyl)thiophen-2-yl)methyl)-4-nitro-2H-1,2,3-triazole (169 mg, 0.67 mmol), iron powder (131 mg, 2.33 mmol) and NH4Cl (215 mg, 3.99 mmol) in a mixture of EtOH (4.6 mL) and water (2.4 mL) was stirred at 50° C. for 30 min. The reaction mixture was filtered while hot and concentrated under reduced pressure. CH2Cl2 (20 mL) was added followed by 3N NaOH (5 mL). The layers were separated and the aq. layer was extracted with CH2Cl2 (3×15 mL). 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 07: tR=0.58 min, [M+H]+=225.18.
