| titleOfInvention | A kind of preparation method of stryphnonasal |
| abstract | The present invention relates to a kind of preparation methods of stryphnonasal, and during preparing stryphnonasal using chloracetyl catechol and methylamine, control reaction carries out in alcoholic solution, and selects four butyl bromation amine or tetrabutylammonium iodide as phase transfer catalyst.Method of the present invention is carried out in alcoholic solution by controlling reaction, the abundant progress of reaction is promoted, while four butyl bromation amine or tetrabutylammonium iodide is added as phase transfer catalyst, accelerates reaction speed, the reaction time is shortened, the accumulation of impurity is reduced.Without purification, the stryphnonasal of high quality can be once prepared, provides the intermediate of high quality to prepare L- adrenaline. |
