Reaction Steps

To a solution of ethyl (trans-4-{[4-(benzyloxy)-3-methylquinolin-2-yl]methoxy}cyclohexyl)carbamate (153 mg) in ethanol-THF (1:1, 6 mL) was added 5% Pd—BaSO4 (70 mg) under nitrogen atmosphere, followed by stirring at room temperature under hydrogen atmosphere for 1 hour. The catalyst was removed by filtration, and then the solvent was evaporated under reduced pressure. The resulting residue was purified by silica gel column chromatography (eluent: chloroform/methanol=95/5). The resulting solid was washed with ethyl acetate and dried to obtain ethyl {trans-4-[(3-methyl-4-oxo-1,4-dihydroquinolin-2-yl]methoxy]cyclohexyl}carbamate (88 mg) as a crystal.
