실험 절차
To a suspension of 189.1 mg (0.50 mmol) of 4-(2,4-dichloroanilino)-7-hydroxybenzo[g]quinoline-3-carbonitrile, 207.2 mg (0.79 mmol) of triphenylphosphine and 66.9 mg (0.75 mmol) of 2-(dimethylamino)-ethanol in 3.0 mL of anhydrous methylene chloride at 0° C. is added dropwise diethyl azodicarboxylate. The resulting reaction mixture is stirred at room temperature under nitrogen for 2 days. The solvent is concentrated in vacuo and the residue is purified on preparative thin layer chromatography (developing solvent: 9:1 methylene chloride/methanol) to provide 46.3 mg (20.5%) of 4-(2,4-dichloroanilino)-7-[2-(dimethylamino)ethoxy]benzo[g]quinoline-3-carbonitrile as a yellow solid, mp 115–117° C.
