Procedure

A solution of EXAMPLE 299E (146.6 mg) in dichloromethane (10 mL) was cooled in an ice bath and 2,2,2-trifluoroacetic acid (5 mL) was added dropwise over 5 minutes. The reaction mixture was stirred 15 minutes under nitrogen, the ice bath was removed and the reaction was allowed to come to ambient temperature. The reaction was stirred 1.5 hours and then concentrated. The crude material was purified by reverse phase chromatography with ammonium acetate buffer in acetonitrile to give the title compound. 1H NMR (300 MHz, dimethyosulfoxide-d6) δ 10.86 (d, 1H), 8.39 (d, 1H), 8.33 (t, 1H), 8.06 (br s, 1H), 7.71 (dd, 1H), 7.53 (d, 1H), 7.34 (d, 2H), 7.26 (d, 1H), 7.19 (d, 1H), 7.05 (m, 3H), 6.89 (d, 1H), 6.70 (dd, 1H), 6.52 (dd, 1H), 6.15 (d, 1H), 3.83 (dd, 2H), 3.22 (m, 3H), 2.82-3.00 (m, 8H), 2.72 (s, 2H), 2.16 (m, 6H), 1.96 (s, 2H), 1.88 (m, 4H), 1.60 (d, 2H), 1.38 (m, 2H), 1.24 (m, 2H), 0.93 (s, 6H).
