Versuchsvorschrift

Sodium carbonate (1.6 g, 15 mmol) was added to 5-fluoro-2-methoxypyridin-4-ylboronic acid (1.0 g, 6.0 mmol) and 2,4-dichloropyrimidine (0.75 g, 5.0 mmol) in 4:1 dioxane/water (25 mL), and the suspension was purged with argon. PdCl2(dppf)*DCM (0.21 g, 0.25 mmol) was added, and the mixture was heated at 80° C. under argon overnight. The reaction mixture was diluted with water, and the resulting solid was collected by vacuum filtration, washed with water, and dried to provide the desired 2-chloro-4-(5-fluoro-2-methoxypyridin-4-yl)pyrimidine (1.2 g, 5.0 mmol, 99% yield) as a solid.
