Procedure
1.14 g (0.0382 mol) of 80% sodium hydride were added at 25° C. under nitrogen to 70 ml of benzyl alcohol, and this mixture was stirred at 100° C. for 30 minutes. After it had been cooled to 40° C., 5.0 g (0.0382 mol) of 2-amino-4,6-difluoropyrimidine were added, and the mixture was then stirred at 100° C. for 5 hours. After the reaction was complete, a little precipitate was filtered off, and the filtrate was concentrated under 1 mbar at a bath temperature of 150° C. The viscous residue obtained in this way was induced to crystallize by trituration with cyclohexane. 6.3 g (75.2% of theory) of the title compound of melting point 96°-98° C. were obtained after filtering off, washing with water and drying.
