Set up the Schlenk line, ensuring it is properly connected to both the inert gas source and the vacuum pump. Evacuate the system by opening the vacuum valve, removing all air from the Schlenk flask. Close the vacuum valve and open the inert gas valve to fill the flask with nitrogen or argon. Repeat the evacuation and gas filling cycles to ensure complete removal of air and moisture. Add reagents to the flask using a syringe or cannula under the inert atmosphere.
