実験手順

In a mixture of ethanol (20 mL) and ethyl acetate (10 mL) was suspended 3-nitro-7-(5-methyl-2-phenyl-4-oxazolylmethoxy)quinoline (740 mg, 2.1 mmol.), and to the suspension was added 10% palladium/carbon (50 mg). Then, catalytic reduction was performed overnight. After the completion of reaction was confirmed, the reaction mixture was filtered over Celite®, and the filtrate was placed under reduced pressure to remove the solvent. The residue was purified by silica gel column chromatography (hexane/ethyl acetate=1/7 to ethyl acetate), to give 280 mg of the desired compound as brown oil (yield 42%).
