実験手順

To 15 mL of methanol containing 4.02 g of 4-hydroxyquinoline and 130 mL of an acetonitrile solution, 5.01 g of diisopropylethylamine and 19.4 mL of a 2.0 mol/L trimethylsilyldiazomethane/hexane solution were added at room temperature, and the mixture was stirred for 13 hours, and the solvent was removed under reduced pressure. The residue thus obtained was purified by silica gel column chromatography [silica gel; Chromatorex-NH, manufactured by Fuji Silysia Chemical Ltd., eluent; hexane:ethyl acetate 2:1] to obtain 1.79 g of a yellow oily substance, 4-methoxyquinoline.
