Procedure
To a solution of Example 2 (0.1 g, 0.249 mmoles) in methanol (10 ml), palladium on carbon 20 mg) was added and the solution was hydrogenated at RT under 5 kg/cm2 pressure of hydrogen for 4 h. The solution was filtered through celite and concentrated. The crude product was purified by column chromatography with ethyl acetate: petroleum ether to afford the title compound as brown solid (0.080 g, 87% yield).: 1H-NMR (δ ppm, DMSO-D6, 400 MHz): δ 8.08(d, J=7.8 Hz, 1H), 7.90(t, J=7.4 Hz, 1H), 7.74 (d, J=8.4 Hz, 1H), 7.55(t, J=7.4 Hz, 1H), 7.49(m, 3H), 7.31(d, J=6.5 Hz, 2H), 3.72(br s,4H), 3.42(br s, 6H).
