Procedure

A solution of EXAMPLE 483D (50 mg) in dioxane (12 mL) and pyridine (1.2 mL) was cooled in an ice-water bath. The mixture was slightly warmed by removing the ice bath and then trifluoroacetic acid (0.3 mL) was added. The reaction was stirred for 1 hour and quenched with methanol and aqueous NaOH. The resulting mixture was stirred for 1 hour and concentrated. The residue was purified by reverse phase HPLC, and eluted with 40%-70% acetonitrile in 0.1% trifluoroacetic acid water over 40 minutes. The desired fractions were concentrated to remove acetonitrile, neutralized with NaHCO3 and extracted with dichloromethane. The dichloromethane layer was dried over Na2SO4, filtered, concentrated and dried to provide the title compound. 1H NMR (400 MHz, dimethylsulfoxide-d6) δ 13.10 (s, 1H), 8.27 (d, 1H), 7.85 (d, 1H), 7.80 (s, 1H), 7.58 (d, 1H), 7.37 (d, 2H), 7.02-7.11 (m, 4H), 6.80 (dd, 1H), 6.54 (d, 1H), 6.14 (d, 1H), 4.19 (d, 2H), 3.22 (s, 4H), 2.97 (s, 2H), 2.59-2.71 (m, 1H), 2.41 (s, 2H), 2.18 (s, 2H), 2.05 (dd, 2H), 1.98 (s, 2H), 1.79-1.90 (m, 3H), 1.47-1.62 (m, 2H), 1.42 (t, 2H), 1.04-1.19 (m, 2H), 0.94 (s, 6H).
