反応手順
6-Hydroxy-3-nitroquinoline (148 mg, 0.78 mmol) was dissolved in THF (18 mL). 2-(Pyrrolidin-1-yl)ethanol (0.091 mL, 0.78 mmol) and triphenylphosphine (306 mg, 1.17 mmol) were added. Lastly, diethyl azodicarboxylate (0.184 mL, 1.17 mmol) was added and the reaction mixture was allowed to stir at room temperature for 2 hours. The solvent was then concentrated in vacuo and the residue was purified by flash chromatography (SiO2) to yield 134 mg (60%) of 3-nitro-6-(2-(pyrrolidin-1-yl)ethoxy)quinoline. LC/MS (m/z): 288.1 (MH+), Rt 1.80 minutes.
