✦ Synopsis

AbstractÐIn the presence of a catalytic amount of a metal tri¯ate such as Sb(OTf) 3 or Ga(OTf) 3 , 2-methoxynaphthalene reacted with acetic anhydride in nitromethane±lithium perchlorate to afford 2-acetyl-6-methoxynaphthalene, a well-known intermediate for the synthesis of naproxen, in a high yield.
