Acetone → Methyl 6-hydroxy-2-naphthoate

Participants

Reaction Steps

In the case where 1.0 g of the present compound, methyl 2-(2-hydroperoxy-2-propyl)naphthalene-6-carboxylate are heated in 10.0 g of acetone for 30 min at a temperature between 50° and 70° C. in the presence of 0.02 g of sulfuric acid as a catalyst, methyl 2-hydroxynaphthalene-6-carboxylate is formed nearly quantitatively. The thus formed compound is hydrolyzed nearly quantitatively into 2-hydroxynaphthalene-6-carboxylic acid (acid-6) by heating the thus formed compound for 30 min at a temperature between 20° and 50° C. in an aqueous about 1N alkali solution.
