The mixture was transferred to a 50 mL round bottom and neutralized with 2 mL of 0.5 N sodium methoxide. The solvent was rotovaped down. The residue was taken up in 10 mL of DCM. 1 g of silica gel was added. The solvent was rotovaped down and the pre-adsorbed solids were purified by flash chromatography to give the title compound (67 mg, 0.09 mmol, 56%); 1H NMR (400 MHz, DMSO-d6) δ ppm 10.21 (s, 1H), 9.34 (s, 1H), 8.40 (s, 1H), 8.34 (s, 1H), 8.27 (s, 1H), 8.02 (s, 1H), 7.80 (s, 1H), 7.73 (s, 1H), 7.65 (s, 1H), 7.59 (s, 1H), 7.46 (s, 1H), 7.38 (s, 1H), 7.18 (s, 2H), 6.96 (s, 2H), 6.72 (s, 1H), 6.46 (s, 1H), 4.02-4.11 (m, 2H), 2.60-2.71 (m, 2H), 2.25-2.32 (m, 10H), 2.12 (s, 3H), 1.26 (s, 3H).
