Participants

Reaction Steps

To a solution of 2-chloro-6-{3-[3-cyclohexyl-3-(2-hydroxybutyl)ureido]-propoxy}quinoline (6.3 g), 4-dimethylaminopyridine (0.1 g) and triethylamine (2.3 g) in methylene chloride (80 ml) is added dropwise with stirring acetic anhydride (1.8 g) at room temperature. The methylene chloride layer is washed successively with diluted hydrochloric acid, water and a saturated aqueous sodium hydrogen carbonate solution, and dried over anhydrous magnesium sulfate. The resultant is concentrated under reduced pressure to remove the solvent to give 2-chloro-6-[3-[3-cyclohexyl-3-(2-acetyloxybutyl)ureido]-propoxy]quinoline (6.7 g) as a colorless oil.
