Versuchsvorschrift
A mixture of 4,6-dichloropyrimidine-2,5-diamine (28 g, 156 mmol), ethanolamine (18 ml, 312 mmol) and ethanol (250 ml) were heated at 100-110° C. for 16 hours. The mixture was cooled and solvent was removed. To the residue methanol (100 ml) was added and stirred for 20 minutes. The solid was filtered off to obtain 2-[(2,5-diamino-6-chloro-pyrimidin-4-yl)amino]ethanol (22.0 g, 70%).
