Procedure

22.4 g (0.15 mol) of 4,6-dichloropyrimidine were introduced into 250 ml of methanol. 27 g of a 30% strength sodium methylate solution were added dropwise at 0° C. After concentration, the mixture was worked up using a water/methylene chloride mixture. 15.0 g (69.2% of theory) of yellow crystals were obtained; m.p. 32°-34° C.
