Steps:

8
Accurately weigh 0.005mmol (l. Lmg) of the transition metal, add 10mL has been put into the magnetic stirrer Young's reaction tube, The oxygen reaction was carried out in the Young's reaction tube, and the reaction was carried out under oxygen conditions. The syringe was applied to the Young's reaction tubeAdd 0.04 mmol of co-catalyst I, 0.08 mmol of co-catalyst II, 0.2 mmol of 4-fluoroaniline and 1 ml of absolute ethanol,The above-mentioned Young's reaction tube was placed on a magnetic stirrer and stirred at 150 ° C for 18 hours. After the completion of the reaction, the pH of the reaction solution was adjustedThe reaction solution was post-treated to give pure 2-methyl-6-fluoro-quinoline in 75% yield.
