Convenient Syntheses of Nabumetone

Abstract
Two novel and convergent one- and two-step syntheses of 4-(6′-methoxy-2′-naphthyl) -2-butanone (nabumetone, 6) via palladium-catalyzed coupling of 2-halo-6-methoxynaphthalene (1) with 3-buten-2-ol (2) and 3-buten-2-one (3) are described. The product is obtained in 60-92% yield.
