Sodium Thiosulfate → HCID 18472671, compound

Participants

Reaction Steps

To a solution of (E)-N-[4-(3-pyridyl)phenyl]-3-(4-methylphenyl)cinnamamide (250 mg) in tetrahydrofuran (20 ml) was added 3-chloroperbenzoic acid (70%, 0.24 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 and extracted with dichloromethane. 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-tetrahydrofuran-acetone to give (E)-N-[4-(1-oxidopyridin-3-yl)phenyl]-3-(4-methylphenyl)cinnamamide (Compound 193) (208 mg) as pale yellow crystals. 1H-NMR (200 MHz, DMSO-d6) δ 2.38 (3H, s), 6.95 (1H, d, J=15.7 Hz), 7.31 (2H, d, J=8.1 Hz), 7.45-7.57 (2H, m), 7.59-7.94 (12H, m), 8.19 (1H, d, J=6.5 Hz), 8.58 (1H, s).
