Procedure

A solution of 3-cyano-6-(2-methoxy-4-methylthiophenyl)-2(1H)-pyridinone (1.24 g) in dichloromethane (500 ml) was treated with m-chloroperbenzoic acid (85%, 0.92 g). After 2 hours the solution was washed with sodium bicarbonate solution and evaporated to give the crude product (1.27 g, m.p. 239-241° C.). Purification by chromatography (silica, dichloromethane) followed by recrystallization from aqueous ethanol yielded the pure title compound, 0.81 g, m.p. 243-245° C.
