Reaktionsschritte
A solution of 5-(2-fluoro-3-pyridinyl)-2,4-bis(methyloxy)pyrimidine (Prep87, 2.8 g, 11.90 mmol) in HCl 4M in 1,4dioxane (42 mL, 168 mmol) was heated at 90° C. for 1 h. A white precipitate crashed out of the solution. Volatiles were evaporated under reduced pressure to give title compound, pale yellow solid (2.75 g).
