Procedure

To a solution of (E)-N-[4-(2-pyridylmethyl)phenyl]-3-(4-methylphenyl)cinnamamide (302 mg) in tetrahydrofuran (10 ml) was added 3-chloroperbenzoic acid (70%, 0.27 g) at 0° C., and the mixture was stirred at room temperature for 18 hours. To the reaction mixture was added sodium thiosulfate solution, and the mixture was stirred for a few minutes. The mixture was extracted with ethyl acetate. The organic layer was washed with saturated sodium bicarbonate solution and saturated sodium chloride solution, dried with magnesium sulfate and concentrated. The residue was recrystallized from ethanol to give (E)-N-[4-(1-oxidopyridin-2-ylmethyl)-phenyl]-3-(4-methylphenyl)cinnamamide (Compound 191) (180 mg) as pale yellow crystals.
