Participants

Reaction Steps

To a solution of Example 107 (0.080 g, 0.149 mmoles) in ethanol (5 ml), Con.HCl (0.5 ml) was added and refluxed for 2 h. The reaction mixture was basified with sodium carbonate solution and extracted with ethyl acetate. The organic layer was dried over sodium sulphate and concentrated under reduced pressure. The crude product was purified by column chromatography with methanol:dichloromethane to afford the title compound as brown solid (0.020 g, 27% yield). MP: 91-94° C. 1H-NMR (δ ppm, DMSO-d6, 400 MHz): δ 8.04 (dd, J=8.3, 1.5 Hz, 1H), 8.02 (s, 1H), 7.85 (m, 1H), 7.67 (d, J=8.4 Hz, 1H), 7.53 (t, J=7.6 Hz, 2H), 7.29 (m, 3H), 7.06 (dt, J=8.7, 2.3 Hz, 1H), 6.91 (br s, 1H), 6.68 (d, J=8.4 Hz, 2H), 6.00 (q, J=7.0 Hz, 1H), 5.42 (s, 2H), 1.87 (d, J=7.0 Hz, 3H). Mass: 492.83 (M+).
