Procedure

24.5 g (0.1 mole) of 2-(4-nitro-phenoxy)-4,6-dimethyl-pyrimidine were dissolved in 150 ml of dioxane and subjected to exhaustive hydrogenation with hydrogen in the presence of Raney nickel under a pressure of 50 bar at a temperature between 20° and 50° C. The catalyst was then filtered off with suction and the filtrate was evaporated under reduced pressure. 20.4 g (95% of theory) of 2-(4-amino-phenoxy)-4,6-dimethylpyrimidine were obtained in the form of a solid substance.
