Procedure
A portion (440 mg, 1.46 mmol) of the 1-(2-acetamido-4-nitrophenoxy)-2-bromoethane produced in (2) above was dissolved in dimethylformamide (5 ml) and, thereafter, potassium iodide (267 mg, 1.608 mmol) and 2-(3,4-dimethoxyphenyl)-N-methylethylamine (0.81 ml, 4.36 mmol) were added to the solution, which was stirred at 70° C. for 1.5 h. Thereafter, the solvent was evaporated from the reaction mixture and the residue was subjected to extraction with ethyl acetate. The organic layer was washed with water four times and dried with sodium sulfate, followed by evaporation of the solvent, with the resulting residue being purified by being subjected to column chromatography on silica gel using, as an eluent, chloroform containing methanol (6%) to yield the end compound 1-(2-acetamido-4-nitrophenoxy)-2-[N-(3,4-dimethoxyphenethyl)-N-methylamino]ethane (590 ml) as a yellow caramel-like substance.
