After cooled to 0° C., 0.1 ml of acetyl chloride was slowly added dropwise. The solution was agitated for 1 hour, and water was added to the solution. The solution was extracted with dichloromethane and washed with water. The dichloromethane layer was dried with anhydrous magnesium sulfate. The dichloromethane was removed by vacuum distillation to give 195 mg of 3-acetoxy-8-methoxy quinoline as an oil.
