To a mixture of 7-(1-azidoethyl)-6-bromo-3-methyl-5H-[1,3]thiazolo[3,2-a]pyrimidin-5-one (0.10 g, 0.32 mmol), and 2-(tributylstannyl)-1,3-thiazole (143 mg, 0.382 mmol) in 1,4-dioxane (3 mL) was added tetrakis(triphenylphosphine)palladium(0) (18 mg, 0.016 mmol). The reaction mixture was heated at 120° C. overnight. After cooling to room temperature, the mixture concentrated under reduced pressure. The crude mixture was purified on silica gel, eluting with 0 to 60% ethyl acetate in hexane, to give the desired product (73 mg, 72%). LCMS calculated for C12H11N6OS2(M+H)+: m/z=319.0. Found: 319.0.
