Reaction Steps

A mixture of Example 12 (80 mg, 0.2 mmol) and LiOH (24 mL, 1 mmol) in methanol (10 mL), THF (10 mL), and water (10 mL) was heated to reflux overnight, cooled to room temperature, and adjusted to pH <5 with concentrated HCl. The solid was collected by filtration to provide 55 mg of the desired product. MS (DCI) m/e 377 (M+H)+; 1H NMR (300 MHz, DMSO-d6) δ 12.65 (s, 1H), 9.89 (s, 1H), 9.28 (s, 1H), 8.33 (s, 1H), 7.75 (d, J=8.1 Hz, 1H), 7.57 (d, J=1.7 Hz, 1H), 7.52 (dd, J=8.1, 1.6 Hz, 1H), 7.24 (d, J=1.7 Hz, 1H), 7.17-7.20 (m, 2H), 7.04-7.10 (m, 2H), 6.88 (d, J=8.1 Hz, 1H), 3.86 (s, 3H).
