PROCEDURE

实验过程

A solution of 4.4 g of [3-(2-amino-3-nitro-phenylcarbamoyl)-propyl]methyl-carbamic acid tert-butyl ester in 36 mL of acetic acid was heated at 90° C. for 5 h and concentrated in vacuo. The residue was taken up in DCM, washed with sat. NaHCO3 solution, dried over anh. Na2SO4 and concentrated in vacuo to yield 3.8 g of methyl-[3-(4-nitro-1H-benzoimidazol-2-yl)-propyl]-carbamic acid tert-butyl ester as dark yellow oil.
