Procedure

4,6-Dichloro-5-(o-methoxyphenoxy)-2-(4-pyridyl)-pyrimidine (2.9 g, Referential Example 1d)) was suspended in dioxane (30 ml) and ammonia (gaseous) was introduced until the solution was saturated. Stirring was continued for 7 days while the saturation of the reaction mixture with ammonia (gaseous) was repeated every 16 to 20 h. The solvent was evaporated, water was added to the residue and the precipitate was filtered off. After drying at HV/50° C. 4-amino-6-chloro-5-(o-methoxyphenoxy)-2-(4-pyridyl)-pyrimidine (2.7 g) was obtained.
