実験手順
A solution of 3-amino-6-(4-fluorophenyl)picolinamide (2.48 g) and triphosgene in 1,4-dioxane (50 mL) was heated to 100° C. for 1 hour. Cooling and filtration provided 2.2 g of 6-(4-fluorophenyl)pyrido[3,2-d]pyrimidine-2,4-diol which was characterized by its mass spectrum as follows: MS (m/z) 258 [M+H]+.
