Komponenten

Versuchsvorschrift

To a mixture containing 7.25 g (0.05 mol) 6-hydroxy-quinoline, 8.25 g (0.05 mol) 2-amino-4,6-dichloropyrimidine in 300 mL of water/acetone 1:1 are added 2.0 g (0.05 mol) sodium hydroxide. On heating a clear solution is first obtained from which a thick precipitate separates. Stirring under reflux is continued for a total of 6 h. The mixture is cooled, filtered and the solid washed with acetone/water 1.1 and dried. The title compound is obtained as a solid: map. 248-250° C.; MS: [M+1]+=273; HPLC: CtRet=1.30; TLC (dichloromethane/methanol 95:5): Rf=0.46.
