실험 절차

According to the method of R. Iemura et al., J. Med. Chem., 29 1178-1183 (1986), combine 1-chloro-2-nitrobenzene (69.0 g, 440 mmol) and 2-aminoethyl ethyl ether (102.5 g, 1.15 mol) and heat to reflux. After 18 hours, cool and dilute the reaction mixture with ethyl acetate (400 mL). Extract with brine. Dry the organic layer over Na2SO4, filter, and evaporate in vacuo to give a residue. Chromatograph the residue on silica gel eluting with dichloromethane to give N-(2-ethoxyethyl)-2-nitroaniline.
