Procedure

Benzyl (2,5-difluoro-4-hydroxyphenyl)carbamate (4.90 g) was dissolved in N,N-dimethylformamide (30 ml), then 4,6-dichloropyrimidine (2.61 g) and potassium carbonate (3.63 g) were added thereto at room temperature, followed by stirring for 2 hr. Water (90 ml) was added to the reaction mixture to precipitate crystals. The crystals were collected by filtration and washed with water (30 ml, 6 times). The crystals were hot air-dried at 60° C. for 2 days to provide the titled compound as pale brown crystals (6.108 g, 89%).
