Versuchsvorschrift

2.7 g (0.015 mol) of 30% strength sodium methylate were added to 2.95 g (0.015 mol) of 2-amino-4-fluoro-6-trifluoromethoxypyrimidine in 50 ml of methanol in the course of 15 minutes while stirring at from -5° to 0° C. After stirring for 1 hour at 0° C. and heating to 25° C., the reaction mixture was evaporated down under reduced pressure, stirred with water and extracted with methylene chloride. Drying and evaporating down under reduced pressure gave 3.1 g (98% of theory) of the title compound of nD25 =1.4770.
