标题 :Process for the synthesis of nabumetone
发明人：CANNATA VINCENZO; BERTONI AMILCARE; BIANCHI STEFANO
权利人:HONEYWELL INT INC
摘要:New process for the synthesis of the antiinflammatory drug known as nabumetone that consists in reacting 2-acetyl-5-bromo-6-methoxynaphthalene with an alkyl acetate in presence of an alkaline alcoholate to get 4-(5-bromo-6-methoxy-2-naphthyl)-4-hydroxybut-3-en-2-one that by catalytic hydrogenation in a polar solvent and in presence of a base gives 4-(6-methoxy-2-naphthyl)butan-2-one known as nabumetone.
