Production of 6-bromo-2-methoxynaphthalene and its derivatives |
| abstract |
(57) [Summary]nIn the preparation of 6-bromo-2-methoxynaphthalene and its derivatives such as nabumetone and naproxen, the reaction between 6-bromo-2-naphthol and dimethyl sulfate is carried out in substantially stoichiometric amounts of sodium hydroxide and water. And in an organic solvent to obtain a high yield of product while preventing the formation of methyl sodium sulfate. |
