Reaction Steps

To a solution of methyl 3-benzyloxy-5-bromo-4-oxo-4H-pyran-2-carboxylate (2.3 g) in dioxane (25 ml) were added tetrakis(triphenylphosphine)palladium(0) (1.57 g) and (2-thiazolyl)tributyltin (5.08 g) under an argon stream, and the mixture was stirred at 100° C. for 1.5 hr. The obtained reaction mixture was concentrated, and subsequently purified by silica gel column chromatography (ethyl acetate:hexane=1:4–1:2) to give methyl 3-benzyloxy-4-oxo-5-(thiazol-2-yl)-4H-pyran-2-carboxylate (1.47 g).
