O-alkylation and intramolecular condensation reactions, starting from readily availablesubstituted o-hydroxy aryl ketone, and chloroacetyl arylamides. This metal-free transition process ischaracterized by mild reaction conditions, atom economy, short reaction time and a high yield with a decreasedamount of by-products.Key Words : Benzofuran, o-Hydroxy aryl ketone, Amine, Synthesis, Intramolecular condensat
