Procedure
At -75° to -70° C. and over a period of 1 hour, 4.7 g (0.278 mol) of gaseous ammonia was gassed, while stirring, into a mixture of 38.0 g (0.147 mol) of 2-fluoro(chloro)-4-trifluoromethoxy-6-trifluoromethylpyrimidine in 150 ml of diethyl ether. The mixture was stirred for 2 hours at -75° C. and for 2 hours at 25° C. The precipitate was suction filtered, and the organic phase was extracted with water, dried and partially evaporated down. Chromatography with methyl tert-butyl ether over silica gel gave 20.4 g (56.1% of theory) of the title compound of melting point 47°-49° C.
