실험 절차

6 g of D-lysine monohydrochloride were dissolved in 180 ml of an aqueous 95% acetic acid solution, and 0.34 ml of salicylaldehyde was added thereto. The mixture was stirred at 100° C. for 3 hours. After the reaction, the mixture was condensed. 30 ml of 50% ethanol-acetone were added to the residue, and the crystalline precipitates were collected by filtration. 5.6 g of DL-lysine monohydrochloride were thereby obtained.
