Procedure

A solution of EXAMPLE 403H (174 mg) and dichloromethane (25 mL) was cooled in an ice bath and 2,2,2-trifluoroacetic acid (25 mL) was added slowly dropwise. The reaction mixture was stirred 30 minutes under nitrogen and the ice bath was removed. The reaction was stirred 18 hours and then concentrated. The crude product was purified by reverse phase chromatography with ammonium acetate buffer in acetonitrile to give the title compound. 1H NMR (400 MHz, pyridine-d5) δ 9.30 (d, 1H), 8.69 (t, 1H), 8.59 (s, 1H), 8.42 (dd, 1H), 7.99 (d, 1H), 7.53 (d, 1H), 7.43 (d, 2H), 7.26 (m, 1H), 7.18 (m, 1H), 7.06 (d, 2H), 6.94 (d, 1H), 6.72-6.66 (m, 2H), 5.53 (m, 2H), 3.98 (m, 2H), 3.32 (m, 2H), 3.18 (t, 2H), 2.03 (m, 4H), 2.76 (s, 2H), 2.25 (m, 2H), 2.13 (m, 4H), 1.97 (s, 2H), 1.83 (m, 1H), 1.60 (m, 2H), 1.40-1.29 (m, 4H), 0.94 (s, 6H).
