PROCEDURE

实验过程

In a flame dried round-bottomed flask equipped with a magnetic stir bar and under inert atmosphere (N2), a solution of 2-[2-(tert-butyl-dimethyl-silanyloxymethyl)-oxazol-4-ylmethyl]-4-nitro-2H-[1,2,3]triazole (103 mg, 0.30 mmol), iron powder (51 mg, 0.91 mmol) and NH4Cl (82 mg, 1.52 mmol) in a mixture of EtOH (3.0 mL) and water (1.5 mL) was stirred at 75° C. for 90 min. The reaction mixture was filtered while hot and concentrated under reduced pressure. The residue was redissolved in CH2Cl2 (20 mL), dried over Na2SO4, filtered, and the solvents were removed under reduced pressure to give the title compound as a yellow oil. TLC:rf (19:1 CH2Cl2-MeOH)=0.20. LC-MS-conditions 02: tR=0.96 min; [M+H]+=310.46.
