Participants

Reaction Steps

To a solution of 433 (78 mg, 0.118 mmol) in MeOH (3 mL) was added 1N NaOH (0.59 mL, 0.59 mmol) and stirred at RT for 3 h. The mixture was then concentrated, diluted with water and the pH was adjusted to 6-7 by addition of 1N HCl. To the resulting suspension was added MeOH to dissolve the mixture clearly, and purified via Biotage [KP-C18-HS 30 g, gradient 20-95% (methanol/water)]. Title compound 434 was obtained as a white solid (79.5 mg, 60% yield). 1H NMR (400 MHz, DMSO-d6) δ (ppm): 10.94 (brs, 1H), 8.71 (s, 1H), 8.62-8.57 (m, 1H), 8.38 (d, J=5.6 Hz, 1H), 8.19 (s, 1H), 8.15 (d, J=8.0 Hz, 1H), 7.89 (dd, J=8.0, 2.0 Hz, 1H), 7.82 (dd, J=14.0, 2.4 Hz, 1H), 7.20 (t, J=9.2 Hz, 1H), 7.09-7.05 (m, 1H), 6.42 (d, J=4.8 Hz, 1H), 6.22 (t, J=5.6 Hz, 1H), 3.84-3.72 (m, 5H), 3.63-3.58 (m, 2H), 3.01-2.94 (m, 2H), 2.86 (s, 2H), 2.59-2.50 (m, 1H), 0.97 (t, J=7.2 Hz, 3H), 0.61-0.56 (m, 2H), 0.45-0.40 (m, 2H). MS (m/z): 634.60 (M+H).
