Reaktionsschritte

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