A suspension that consists of 1.06 g (7.95 mmol) of aluminum chloride in 35 ml of toluene is mixed with 1.70 ml (15.7 mmol) of diethylamine while being cooled with ice. After one hour at room temperature, 350 mg (1.73 mmol) of 5-aminoquinoline-2-carboxylic acid methyl ester is added, and the reaction mixture is allowed to stir for 5 hours at 40° C. The reaction is halted by adding water. It is extracted with dichloromethane, and the combined organic phases are dried on sodium sulfate. After removal of the solvent and purification on silica gel with dichloromethane-methanol (0-10%), 210 mg (50% of theory) of the product is obtained.
