After the reaction has progressed to completion (monitor by TLC or other suitable analytical techniques), add a small amount of acetic acid (usually 1-2 mL) to the reaction mixture to quench any remaining oxidizing agents and to adjust the pH to acidic conditions. The mixture can be stirred for a short time to ensure the completion of the quenching reaction.
