Versuchsvorschrift
30.0 g (0.20 mol) of 2,4-dichloropyrimidine, 30.9 g (0.20 mol) of ethyl N-methylglycinate and 61.0 g (0.60 mol) of triethylamine in 200 ml of dioxane are stirred at 50° C. for 10 min. The mixture is filtered off with suction and the mother liquor is concentrated to half the original volume. A solid crystallizes out, which is filtered off with suction. The mother liquor is concentrated, the residue is stirred with petroleum ether and the product is filtered off.
