The present invention relates to a process for the preparation of amines, comprising the following steps: a. reaction of a (i) carboxylic acid amide of the general formula (I), or (ii) carboxylic acid diamide of the general formula (II), or (iii) di-, tri- or polypeptide, or (iv) peptide amide with carboxy-terminal amide function with an alkylating agent, b. addition of a hydrogenation catalyst to the reaction mixture in a molar ratio of from 1:10 to 1:100 000, based on carboxylic acid amide, carboxylic acid diamide, di-, tri- or polypeptide or peptide amide, c. reaction of the reaction mixture with hydrogen, where a hydrogen pressure of from 0.1 bar to 200 bar is established and where a temperature in a range of from 0° C. to 250° C. is established.
本发明涉及一种氨基的制备方法,包括以下步骤:a. 将通式(I)的羧酸酰胺,或通式(II)的羧酸二酰胺,或二肽、三肽或多肽,或带有羧基末端酰胺功能的肽酰胺与烷基化剂发生反应,b. 在摩尔比为1:10至1:100,000的范围内向反应混合物中加入氢化催化剂,基于羧酸酰胺、羧酸二酰胺、二肽、三肽或多肽或肽酰胺,c. 将反应混合物与氢气反应,在此建立氢气压力为0.1巴至200巴,并在0°C至250°C的温度范围内进行反应。
