(2R,3S)-2,3-Dihydroxy-3-(1-(4-((5-(trifluoromethyl)pyridin-2-yl)oxy)phenyl)-1H-indol-3-yl)propanamide (5) was prepared as follows: A solution of compound 4 (100 mg) and NH3 (in MeOH ˜7N, 6 mL) was shaken at room temperature for 72 hours. The solvent was evaporated, and the residue was purified by column (EtOAc/MeOH 8/1.5) to afford compound 5 as a white solid (70 mg): 1H-NMR (400 MHz, CD3OD) δ: 8.49 (s, 1H), 8.06 (1H, dd, 2.6 & 8.7 Hz), 7.82 (1H, d, 7.8 Hz), 7.56-7.65 (m, 4H), 7.38-7.41 (m, 2H), 7.15-7.25 (m, 3H), 5.51 (dd, 1H, 0.8 & 2.6 Hz), 4.37 (1H, d, 2.6 Hz); LC/MS: m/z=480.2 [M+Na+] (Calc: 457.4).
