7.2 g (48.7 mmol) 2,4-dichloropyrimidine are initially introduced into 140 ml water. 5.3 g (48.7 mmol) 3-hydroxyazetidine hydrochloride and 48.7 ml 1 N sodium hydroxide solution are added and the mixture is heated at 90° C. for 72 h (the 2,4-dichloropyrimidine being detectably volatile and precipitating in crystalline form on the condenser). The solvent is removed in vacuo and the residue is dried to give 10.4 g of the crude product, which is reacted without further purification.
