实验过程

1 ml of developed Raney nickel was added to a methanol (5 ml) solution of 410 mg of t-butyl 2-(4-amino-2-((2′-fluorobiphenyl-4-yl)oxy)-5-nitrophenyl)pyrrolidine-1-carboxylate, and the reaction liquid was stirred in a hydrogen atmosphere at room temperature for 1 day. The catalyst was removed through filtration through Celite, and the solvent was evaporated away under reduced pressure, and the residue was purified through silica gel column chromatography (developing solvent: hexane/ethyl acetate=1/1) to obtain the entitled compound as a brown oily substance.
