Water → 2-(4-Carboxyphenoxy)-4-chlorobenzoic acid

Participants

Reaction Steps

A mixture of 12 g. of 2-(p-methylphenyloxy)-4-chlorobenzoic acid, 72 g. of potassium permanganate, 200 ml. of t-butanol and 350 ml. of water is refluxed for 4.5 hours. After this time, the t-butanol is distilled off, and the reaction mixture is filtered. The filtrate is acidified to give 2-(p-carboxyphenyloxy)-4-chlorobenzoic acid which can be recrystallized from benzene:heptane.
