Abstract
La presente invención se refiere a un método, caracterizado porque comprende: (a) hacer reaccionar el ácido L-aspártico con ácido fórmico en presencia de una cantidad efectiva de anhídrido acético bajo condiciones suficientes par formar el anhídrido N-formil-L-aspártico; y después (b) adicionar a (a) anterior una cantidad efectiva de un alcohol secundario de 3 a 6 átomos de carbono para consumir el exeso de ácido fórmico, en donde la mezcla de reacción de anhídrido N-formil-L-aspártico resultante es adecuada para reacciones sin modificación .The present invention relates to a method, characterized in that it comprises: (a) reacting L-aspartic acid with formic acid in the presence of an effective amount of acetic anhydride under conditions sufficient to form the N-formyl-L-aspartic anhydride; and then (b) adding to (a) above an effective amount of a secondary alcohol of 3 to 6 carbon atoms to consume the ex-formic acid, wherein the resulting reaction mixture of N-formyl-L-aspartic anhydride is suitable for reactions without modification.
