2-Trifluoromethanesulfonyloxy-8-[2-(4-isopropyl-1,3-thiazol-2-yl)ethyl]-4H-pyrido[1,2-a]pyrimidin-4-one(499 mg), pyridine-3-boronic acid 1,3-propanediol cyclic ester (364 mg), palladium tetrakistriphenylphosphine (65 mg), potassium bromide (146 mg) and potassium carbonate (231 mg) were added with dioxane(8 ml) and stirred overnight at 85° C. under nitrogen atmosphere. The reaction mixture was cooled and then added with ethyl acetate. Insoluble solids were removed by filtration, and the solvent of the filtrate was evaporated. The residue was purified by silica gel column chromatography to obtain the title compound (400 mg).
