Procedure
To a solution of EXAMPLE 521I (0.24 g) dichloromethane (1 mL) was added trifluoroacetic acid (0.5 mL). After stirring for 1 hour, the reaction was concentrated, dissolved in dichloromethane (5 mL) and quenched with saturated NaHCO3 (5 mL). The reaction was diluted with water (10 mL) and saturated NaHCO3 (15 mL) and the product extracted into dichloromethane (2×25 mL). The combined organics were washed with brine (25 mL), dried over magnesium sulfate, filtered, and concentrated. The residue was loaded onto silica gel (Reveleris 40 g) and eluted using a gradient of 0.5% to 3% methanol/dichloromethane over 30 minutes (flow=40 ml/minutes). The product was collected, concentrated, dissolved in acetonitrile and concentrated, and dried in vacuum oven at 75° C. overnight to give the title compound. 1H NMR (300 MHz, dimethylsulfoxide-d6) δ 13.12 (s, 1H), 12.24-11.44 (m, 1H), 8.31 (d, 1H), 7.91 (d, 1H), 7.83 (s, 1H), 7.57 (d, 1H), 7.40 (d, 2H), 7.13 (d, 4H), 6.81 (dd, 1H), 6.56 (d, 1H), 6.16 (dd, 1H), 4.52 (d, 2H), 3.79 (dt, 2H), 3.70-3.51 (m, 2H), 3.20 (s, 4H), 2.76 (dd, 4H), 2.49 (m, 8H), 2.02-1.71 (m, 4H).
