Методика
In this example that demonstrates how this method could be performed, 5 g Lysine, 8.7 g glutaric anhydride and 2.0 g 4-Dimethylaminopyridine (DMAP) are weighed into a 100 ml flask fitted with a condenser and nitrogen inlet. 100 ml DMF is added and the mixture stirred under nitrogen atmosphere for 5 min and immersed into an oil bath preheated to 90° C. for 1.5 h until HPLC assay indicated completion of reaction. DMF is evaporated under vacuum (distilled below 40° C. and the residue is used directly for the subsequent reaction. The residue can be purified by chromatography on silica gel.
