Versuchsvorschrift

To a solution of [4-(benzyloxy)-3-methylquinolin-2-yl]methanol (400 mg) in THF (8 mL) was added (5-indanyl)isocyanate (498 mg), and the mixture was stirred at 40° C. for 15 hours. Methanol (2 mL) was added to the reaction liquid to stop the reaction. Ethanol (10 mL) and 10% palladium-activated carbon (200 mg) were added to this mixture. The mixture was stirred at room temperature under hydrogen atmosphere for 30 minutes. The catalyst was removed by filtration, and then the solvent was evaporated. The residue was purified by silica gel column chromatography (eluent: chloroform/methanol=98/2) to obtain (3-methyl-4-oxo-1,4-dihydroquinolin-2-yl)methyl(2,3-dihydro-1H-inden-5-yl)carbamate (356 mg).
