Procedure

Using the same procedure for the preparation of 5A, treatment of compound 16A (870 mg) with TFA (10 mL) in methylene chloride (10 mL) gives compound 17A in 74.0% yield. 1H NMR (DMSO-d6, 500 MHz) δ 10.67 (s, 1H), 10.02 (s, 1H), 8.35 (s, 1H), 8.28 (s, 1H), 7.73 (d, 2H, J=8.0 Hz), 7.47 (d, 2H, J=8.5 Hz), 7.30 (d, 1H, J=9.0 Hz), 6.99 (d, 1H, J=8.5 Hz), 5.01 (br s, 1H), 4.26 (br s, 2H), 3.83 (d, 1H, J=7.5 Hz), 3.78 (d, 2H, J=2.5 Hz), 3.61 (m, 3H), 3.52 (m, 2H), 3.43 (t, 1H, J=10.0 Hz), 2.85 (d, 1H, J=13.0 Hz), 2.75 (t, 1H, J=11.0 Hz). LCMS (ESI) m/z 467.09 (MH+, 100); HPLC: tR=3.92 min.
