Procedure

To a solution of example 53 (0.190 g, 0.480 mmol) in methanol (2.7 ml), lithium hydroxide (0.201 g, 4.80 mmol) in water (0.75 ml) was added and stirred at RT. After 12 h, the pH was adjusted to 7-7.5 using 0.5N HCl and the solid precipitated was filtered, washed with ethyl acetate and petroleum ether and dried under vacuum to afford the title compound as brown solid (0.070 g, 38%). 1H-NMR (δ ppm, DMSO-d6, 400 MHz): 13.39 (s, 1H), 8.87 (d, J=2.6 Hz, 1H), 8.77 (s, 1H), 8.68 (d, J=8.7 Hz, 1H), 8.39 (m, 2H), 8.16 (d, J=8.7 Hz, 1H), 8.07 (m, 3H). 7.85 (dd, J=8.7, 1.5 Hz, 1H), 7.66 (t, J=7.8 Hz, 1H), 7.52 (dd, J=8.3, 4.1 Hz, 1H), 6.22 (s, 2H).
