Reaction Steps

To a solution of 1-(4-nitrophenyl)-3-(4-trifluoromethoxyphenyl)-1,3-dihydroimidazol-2-one (144 mg, 0.395 mmol) in 40 mL of EtOH was added 100 mg of 10% palladium on carbon. The mixture was evacuated and flushed with nitrogen three times. The Parr vessel was pressurized to 45 psi of hydrogen and shaken for 5 h. The depressurized solution was filtered through a pad of Celite® and the pad was washed with EtOH (25 mL). The ethanol was removed under reduced pressure to afford the title product (114 mg, 95%). 1H NMR (400 MHz, CDCl3) δ 7.61 (d, J=9.2 Hz, 2H), 7.33 (d, J=9.2 Hz, 2H), 7.21 (d, J=8.6 Hz, 2H), 6.71 (d, J=9.2 Hz, 2H), 3.92 (s, 4H), 3.61 (bs, 2H); EIMS 307 (M+).
