Abstract

A one pot process is provided in which a Mannich base of the formula 5 is reacted with acetic anhydride to produce a diacetate derivative. Without any intermediate isolation, the derivative is hydrogenated to produce a reaction mixture containing 1-acetoxy-2-methylnaphthalene which is readily precipitated from the reaction mixture by addition of water. ##STR1##
