実験手順

To a solution of 2-tert-butyldimethylsilyloxy-4-nitroaniline (300 mg, 1.125 mmol) in toluene (10 mL), triphosgene (126 mg, 0.45 mmol) and triethylamine (0.195 mL, 1.35 mmol) were added. The reaction mixture was stirred at 80° C. for 3 hours. Then it was cooled to room temperature and all solvent was evaporated. The residue was dissolved in DMF (1 mL) and 2-benzyloxypropylamine (185.6 mg, 1.125 mmol) was added. The reaction mixture was stirred at 80° C. for 16 hours. Chromatography of the resulting liquid on silica gel (50% Ethyl acetate/Hexane) gave desired product (160 mg, 41%). EI-MS m/z 346.4 (M+). mp: 64.6-65.2° C.
