Reaction Steps

2-chloro-5-methylanisole (31.2 g, 1 equiv) and Bu4NCl (2 g, cat.) in 500 mL of water was treated with 95 g of KMnO4 at reflux for 3 hours. The mixture was then filtered through celite, acidified with conc. HCl and the white solid was collected after filtration and air dry to give 4-chloro-3-methoxybenzoic acid.
