Procedure

To a solution of 1-{2-(2-oxo-4-bis(2-tert-butyldimethylsilyloxyethyl)aminocarbonyl-1,2-dihydroquinolin-1-yl]-4-pyridyl}-2,3-bis(hydroxymethyl)-6,7-dimethoxynaphthalene (1.9 g) in tetrahydrofuran (20 ml) is added a 1.0 M solution of tetrabutylammonium fluoride in tetrahydrofuran (2.8 ml) under ice-cooling, and the mixture is stirred at room temperature for one hour. After the reaction is complete, the mixture is concentrated under reduced pressure to remove the solvent, and to the resultant are added methylene chloride and an aqueous sodium hydrogen carbonate solution. The methylene chloride layer is separated, washed, dried, and concentrated under reduced pressure to remove the solvent. The residue is purified by silica gel column chromatography (solvent; chloroform:methanol=10:1˜5:1), and triturated with ether to give 1-{2-(2-oxo-4-bis(2-hydroxyethyl)aminocarbonyl-1,2-dihydroquinolin-1-yl)-4-pyridyl}-2,3-bis(hydroxymethyl)-6,7-dimethoxynaphthalene (0.68 g) which is listed in Table 7.
