In a flame dried round-bottomed flask equipped with a magnetic stir bar and under inert atmosphere (N2), a mixture of 1-[2-(4-nitro-[1,2,3]triazol-2-ylmethyl)-oxazol-4-yl]-ethanone (48 mg, 0.20 mmol), iron powder (34 mg, 0.61 mmol) and NH4Cl (54 mg, 1.01 mmol) in a mixture of EtOH (2.0 mL) and water (1.0 mL) was stirred at 75° C. for 60 min. The reaction mixture was filtered while hot and concentrated under reduced pressure. The filtrated was dried over Na2SO4, filtered, and the solvents were removed under reduced pressure to give the title compound as a brown oil. TLC: rf (EA)=0.40. LC-MS-conditions 02: tR=0.54 min; [M+H]+=208.44.
