Sodium Bicarbonate → HCID 86705171, compound

Participants

Reaction Steps

A suspension of 2-[(5S)-3-(4-methoxyphenyl)-2-oxo-5-propylimidazolidin-1-yl]-N-[4-(trifluoromethyl)pyridin-2-yl]acetamide (137 mg) in acetonitrile (3 mL) was cooled in ice, and a solution of ammonium cerium nitrate (340 mg) in water (3 mL) was added dropwise thereto. After stirring the mixture at room temperature for 2 hr, an additional solution of ammonium cerium nitrate (100 mg) in water (0.5 mL) was added thereto, and the mixture was stirred at room temperature for 10 min. Saturated aqueous sodium hydrogen carbonate solution was added thereto, the resulting mixture was extracted with ethyl acetate, and then the organic layer was washed with brine, followed by drying over anhydrous magnesium sulfate. After the dissicant was filterred off, the solvent was distilled off under reduced pressure, and the residue was purified by column chromatography (silica gel cartridge, chloroform/methanol=98:2-80:20) to afford the title compound (76 mg). (ESI pos.) m/z: 331 ([M+H]+)
