Procedure

Methanesulfonyl chloride (1.0 ml) was added to a dichloromethane (80 ml) solution of 2.8 g of 7-(4-hydroxy-3-methyl butoxy)-3,4-dihydro-1H-quinolin-2-one and 2.4 ml of triethylamine while being stirred under ice-cooling and stirred at room temperature overnight. Water was added to the reaction solution, which was then extracted with dichloromethane and, after washed with water, dried over magnesium sulfate, and the solvent was evaporated under reduced pressure. The residue was purified by silica gel column chromatography (dichloromethane:methanol=30:1), and methanesulfonic acid 2-methyl-4-(2-oxo-1,2,3,4-tetrahydroquinolin-7-yloxy)butyl ester (2.8 g) was obtained in the form of a green powder.
