Procedure

To a solution of Example 82 (0.075 g, 0.142 mmoles) in dichloromethane (15 ml), BBr3 (1M in dichloromethane, 1 ml) was added at 0° C. and the reaction mixture was warmed to RT and then stirred for 12 h. The reaction mixture was quenched with 1.5N Hal solution and extracted with dichloromethane. The organic layer was dried over sodium sulphate and concentrated. The crude product was purified by column chromatography with methanol: dichloromethane to afford the title compound as pale green solid (0.040 g, 55% yield). MP: 241-244° C. 1H-NMR (δ ppm, DMSO-D6, 400 MHz): δ 10.15(s,1H), 8.05(s, 1H), 8.05(dd, J=8.6,1.5 Hz, 1H), 7.86(m, 1H), 7.68(d, J=8.4 Hz, 1H),7.53(t, J=7.4 Hz, 1H), 7.28(m,2H), 7.20(dd, J=8.5,1.9 Hz, 1H), 7.05(m,4H),6.04(q, J=7.1 Hz, 1H),1.88(d, J=7.1 Hz, 3H). Mass: 511.94(M+).
