実験手順

4.5 g of 5-nitroquinolin-2(1H)-one (Chem. Pharm. Bull. 29, 651 (1981)) is hydrogenated in 200 ml of ethyl acetate and 500 ml of methanol in the presence of 450 mg of palladium on activated carbon as a catalyst under normal pressure with hydrogen until the reaction is completed. The catalyst is removed by filtration through diatomaceous earth, and the reaction solution is concentrated by evaporation in a vacuum. 3.8 g of the title compound is obtained as a yellow solid.
