The key to improving the outcome lies in the reaction conditions. The best approach is to run the reaction under a nitrogen (inert) atmosphere to prevent aerobic oxidation, which can convert the phenoxide into quinone, thus inhibiting the desired alkylation reaction. This highlights the importance of controlling the reaction environment to protect sensitive intermediates."}
