実験手順

{2-[(5-Methyl-furan-2-ylmethyl)-amino]-quinolin-5-yl}-methanol (180 mg, 672 mmol) was dissolved in 12 mL tetrahydrofurane. Phenol (70 mg, 0.745 mmol) and triphenylphosphine (200 mg, 0.763 mmol) were added at room temperature. Diisopropyl azodicarboxylate (159 mg, 0.787 mmol) was slowly added at 0° C. The reaction mixture was stirred at room temperature overnight. The reaction mixture was quenched by addition of 50 mL 2N sodium carbonate. The mixture was extracted three times with dichloromethane (50 mL each). The organic phases ware pooled, dried with sodium sulfate, filtered and evaporated. The residue was purified by flash chromatography on silica gel (cyclohexane/ethyl acetate 100:0->50:50 gradient). The title compound was obtained as a light brown oil (90 mg, 39%), MS: m/e=345.4 (M+H+).
