Procedure

According to general procedure A, from #33 (55 mg, 0.055 mmol, 1 eq.) in dichloromethane (6 mL, 0.009 M) and diethylamine (4 mL) was synthesized the crude desired material, which was purified by silica gel chromatography (Gradient: 0% to 5% methanol in dichloromethane) to give #34 (25 mg, 60%) as a solid. HPLC (Protocol A): m/z 759.4 [M+H+], retention time=7.088 minutes, (purity >75%). 1H NMR (400 MHz, DMSO-d6), presumed to be a mixture of rotamers, characteristic signals: δ [10.54 (br d, J=8 Hz) and 10.81 (br d, J=8 Hz), total 1H], 8.01-8.08 (m, 1H), [7.80 (d, J=3.1 Hz) and 7.83 (d, J=3.3 Hz), total 1H], [7.65 (d, J=3.2 Hz) and 7.69 (d, J=3.2 Hz), total 1H], 7.29-7.33 (m, 2H), 7.20-7.27 (m, 2H), 7.13-7.19 (m, 1H), 6.27-6.35 and 6.40-6.48 (2 m, total 1H), [4.49 (dd, J=9, 8 Hz) and 4.56 (dd, J=9, 8 Hz), total 1H], 3.24 and 3.25 (2 s, total 3H), 3.17 and 3.21 (2 s, total 3H), 2.92 and 2.99 (2 br s, total 3H), 1.20 and 1.21 (2 s, total 3H), 1.12 and 1.13 (2 s, total 3H), 0.75-0.81 (m, 3H).
