实验步骤: The title compound was prepared from 3-(N-tert-butyloxycarbonylaminoethyl)-1-benzhydryl azetidine according the procedure for 3-(N-tert-butyloxycarbonylaminomethyl) azetidine, in a yield of 1.2 g (70%).

反应条件: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

实验步骤: 3.4 g (9.6 mmol) of 3-(N-tert-butyloxycarbonylaminomethyl)-1-benzhydryl azetidine was dissolved in 170 mL MeOH and hydrogenated over 0.30 g Pd(OH)2 at 5 MPa over night. The catalyst was filtered off and the solvent evaporated. The crude product was purified by flash chromatography using MeOH/CH2Cl2, 1/9, followed by MeOH (saturated with NH3 (g))/CH2Cl2, 1/9, as eluent to yield 1.2 g (67%) of the title compound. The catalyst was filtered off the solvent evaporated The crude product was purified by flash chromatography

实验步骤: To a solution of 4′-fluoro-4-nitro-[1,1′-biphenyl]-3-amine (1.5 g, 6.46 mmol) in DCM (50 mL) were added triphosgene (1.917 g, 6.46 mmol) and TEA (8.5 g, 84 mmol) at 0° C. The reaction mixture was stirred at room temperature for two hours. tert-butyl azetidin-3-ylmethylcarbamate (1.203 g, 6.46 mmol) was then added at 0° C. and the reaction mixture was stirred at room temperature for four hours. The reaction crude was diluted with saturated citric acid solution and extracted with DCM. The organic layer was washed with water, brine, dried over Na2SO4, filtered and concentrated to yield crude residue which was purified by column chromatography eluting with 30% EtOAc in Hexane to afford tert-butyl((1-((4′-fluoro-4-nitro-[1,1′-biphenyl]-3-yl)carbamoyl)azetidin-3-yl)methyl)carbamate (2 g, 69.7% yield). the reaction mixture was stirred at room temperature for four hours The reaction crude extracted with DCM The organic layer was washed with water, brine dried over Na2SO4 filtered concentrated to yield crude residue which was purified by column chromatography eluting with 30% EtOAc in Hexane
