Procedure
A solution of methylthiomethyl 3-bromo-4-oxo-6-phenyl-4H-pyran-2-carboxylate (0.36 g) and m-chloroperoxybenzoic acid (0.22 g, 80% pure) in chloroform (5 ml) was stirred for 4 hours at room temperature, filtered, washed with sodium bicarbonate solution, and evaporated. The residue was recrystallised from ethyl acetate-petroleum ether 60°-80° C. to give the title product (mp 159° C.).
