tert-Butyl 2-(diethylphosphono)propionate (70 mg) was dissolved in tetrahydrofuran(5 ml), added with sodium hydride (60% in oil, 40 mg), and stirred for 10 minutes. The reaction mixture was added with 8-(2-(4-isopropyl-1,3-thiazol-2-yl)-ethyl)-4-oxo-4H-pyrido[1,2-a]pyrimidine-3-carbaldehyde (56 mg), stirred for 10 minutes and added with acetic acid (0.2 ml), and then distributed between ethyl acetate and saturated aqueous sodium hydrogencarbonate. The organic layer was concentrated, and the residue was purified by silica gel column chromatography to obtain the title compound (70 mg) as yellow oil.
