| titleOfInvention | Improved Process for the Preparation of Methyl 3-methoxy-4,5-methylenedioxybenzoate |
| abstract | The present invention provides the preparation of dimethyl 4,4'-dimethoxy-5,6,5 ', 6'-dimethylenedioxybiphenyl-2,2'-dicarboxylate (DDB) which is usefully used as an intercalating agent. A modified process for the preparation of methyl 3-methoxy-4.5-methylenedioxybenzoate of the general formula (IV) below, which is used as an intermediate, relates to methyl 3-methoxy-4.5-dihydride of the general formula (III) In preparing methylene 3-methoxy-4.5-methylenedioxybenzoate of the general formula (IV), the reaction of methylene dichloride with oxybenzoate is carried out with cesium carbonate in the presence of dimethylformamide. Provide a method.n n n → n n n (Ⅲ) (Ⅳ)n n n The method of the present invention is superior in yield to the conventional method, and the reaction is carried out simply and quickly. |
