YieldReaction ConditionsOperation in experiment
With sodium hydroxide; In 1-methyl-pyrrolidin-2-one; methanol; water; EXAMPLE 9 Preparation of 2-amino-6-(4-chlorophenoxy)-4-fluoropyrimidine (Variant A) STR17 2.52 g (0.038 mol) of 85% sodium hydroxide were dissolved in 50 ml of methanol, 4.9 g (0.0382 mol) of 4-chlorophenol were added, and the mixture was evaporated to dryness. The residue of salt obtained in this way was taken up in 50 ml of N-methyl-2-pyrrolidone and, at 25 C., 5.0 g (0.0382 mol) of <strong>[675-11-6]2-amino-4,6-difluoropyrimidine</strong> were added, and the mixture was stirred at 140 C. for 4 hours. After the reaction mixture had been cooled to 25 C. it was stirred into 500 ml of water, and the resulting precipitate was isolated. 7.4 g (81% of theory) of the title compound of melting point 223-226 C. were obtained in this way.

YieldReaction ConditionsOperation in experiment
In dichloromethane; EXAMPLE 5 Preparation of 6-allyloxy-2-amino-4-fluoropyrimidine (Variant A) STR13 1.14 g (0.0382 mol) of 80% sodium hydride (emulsion in linseed oil) were added at 25 C. under a nitrogen atmosphere to 70 ml of allyl alcohol. To the clear solution obtained after stirring at 40 C. for 20 minutes were added 5.0 g (0.0382 mol) of <strong>[675-11-6]2-amino-4,6-difluoropyrimidine</strong>, and the mixture was then stirred at 97 C. for 1.5 hours. To work up, the excess alcohol was removed by distillation under reduced pressure, the residue was taken up in methylene chloride, and the solution was washed with water, dried over magnesium sulfate and then freed of solvent. The viscous oil obtained in this way crystallized on trituration with n-pentane. 4.6 g (71.2% of theory) of the title compound of melting point 62-66 C. were obtained after filtering off, washing with water and drying.

In propan-1-ol; water; EXAMPLE 3 Preparation of 2-amino-4-fluoro-6-propyloxypyrimidine (Variant A) STR11 29 4 g (0.3 mol) of potassium propylate were reacted as in Example 1 with 39.3 g (0.3 mol) of <strong>[675-11-6]2-amino-4,6-difluoropyrimidine</strong> in a total of 400 ml of n-propanol. The solvent was removed from the reaction mixture under reduced pressure, and the residue was washed with petroleum ether. It was subsequently stirred in water, filtered off, washed and dried, resulting in 36.1 g (70% of theory) of the title compound of melting point 63-66 C.

YieldReaction ConditionsOperation in experiment
With ammonia; In water; (a) 2-Amino-4,6-difluoropyrimidine 69.7 g (4.1 mol) of liquid ammonia were added at -30 to -20 C. to a stirred mixture of 250 g (1.865 mol) of 2,4,6-trifluoropyrimidine and 3.3 1 of diethyl ether within 1 hour. To work up, the reaction mixture was warmed to 25 C. and the precipitate was filtered off. Washing with ether, stirring in water, renewed filtration and drying resulted in 203 g (83% of theory) of the desired product (melting point 214-216 C.). It was possible by concentrating the ether filtrate to about 1/3 of its volume to isolate a further 20 g (8% of theory) of this compound, of melting point 193-196 C., from a 1:1 mixture with the isomeric 4-amino compound. Comparative experiment (according to SU-A 547,447--1975) Under the same reaction conditions as in (a), but with addition and reaction taking place at -10 C., 100 g (0.746 mol) of 2,4,6-trifluoropyrimidine and 29.1 g (1.71 mol) of ammonia yielded 76 g (78% of theory) of the title compound of melting point 212-213 C., and from the filtrate a further 19.5 g (20% of theory) of a mixture (40:60) of the desired compound and the isomeric 4-amino compound (melting point 195-196 C.).

85% With potassium carbonate; In 1,4-dioxane; N,N-dimethyl-formamide; at 20℃; for 48.0h;Sealed tube; In a sealable tube, a solution of <strong>[675-11-6]4,6-difluoropyrimidin-2-amine</strong> (1.0 g, 7.6 mmol) in 1,4-dioxane/dimethylformamide (20.0 mL, 1:1), potassium carbonate (1.6 g, 11.9 mmol) and tert-butylamine (1.7 g, 23.0 mmol) were added. The resulting reaction mixture was stirred at room temperature for 48 h. After completion, the reaction mixture was concentrated under reduced pressure. The crude material was diluted with cold water (10.0 mL) whereupon a solid formed. The solid was filtered and air dried to afford the title compound S7-2 (1.2 g, 85%) as an off-white solid.
