Participants

Reaction Steps

To a solution of Example 1 (0.1 g, 0.22 mmoles) in methanol (10 ml), palladium on carbon (10 mg) was added and the solution was hydrogenated at RT under 5 kg/cm2 pressure of hydrogen for 3 h. The solution was filtered through celite and concentrated. The crude product was purified by column chromatography with methanol: dichloromethane to afford the title compound as pale yellow solid (0.030 g, 37% yield).: MP: 173-175° C. 1H-NMR (δ ppm, DMSO-D6, 400 MHz): δ 8.10(d, J=12.5 Hz, 1H), 8.05(d, J=8.0 Hz, 1H), 7.77 (t, J=7.7 Hz, 1H), 7.48-7.41(m, 6H), 7.22(s,2H), 5.34(s, 2H). Mass: 370.05(M++1).
