A process for the preparation of a compound having at least one at least mono-substituted amino group

The invention relates to a process for preparing a compound having at least one at least mono-substituted amino group. According to the invention at least one amino group-bearing starting material is reacted with a to a first functional group and at least one further functional group-bearing reagent in a reaction mixture. The first functional group is a hydroxyl group and at least one further functional group is selected from the class comprising hydroxyl groups, mercapto groups, carboxylic acid groups, Carbonsaureestergruppen, carboxylic acid amide groups, ketone groups, carbonate groups, halogens, epoxy groups and carbamate groups which independently in the presence of several further functional groups are independently selected from said class.
