実験手順

N-acetyliminodiacetic acid (XVI) monohydrate (45 g) and varying amounts of water and acetic acid were heated at 175° C. or 195° C. for various periods of time. After cooling to room temperature, the mixture was filtered. The solid was washed with water (10 mL) and dried to give 1,4-di(carboxymethyl)-2,5-diketopiperazine. The table below shows the yields of solid under various conditions.
