| titleOfInvention | The method that a kind of one pot of fusion method of solid phase prepares amikacin intermediate |
| abstract | The invention discloses the method that a kind of one pot of fusion method of solid phase prepares amikacin intermediate, comprising：Catalyst, phthalic anhydride and L α hydroxyl gamma aminobutyric acids are heated to melting, reaction is completed, and post processing obtains amikacin intermediate：(S) α hydroxyls γ N phthaloylamino butyric acid.The method is reacted using solvent-free solid-phase, it is not necessary to which the L HABA of high-purity, easy to operate, high income, chemical purity and optical purity are high, and the reaction time is short, is post-processed simple and easy to apply.If during using solid catalyst such as alkali alumina or weak-base ion-exchange resin, could be with recycled after catalyst upon activation.With fine industrial production prospect. |
