Procedure

According to general procedure A, from #29 (54 mg, 0.054 mmol) in dichloromethane (6 mL, 0.9 mM) and diethylamine (4 mL) was synthesized the crude desired material, which was purified by silica gel chromatography (Gradient: 0% to 10% methanol in dichloromethane) to give example #30 (26 mg, 61%) as a solid. HPLC (Protocol A): retention time=7.233 minutes, m/z 785.4 [M+H+], (purity >72%). 1H NMR (400 MHz, DMSO-d6), presumed to be a mixture of rotamers, characteristic signals: δ [10.54 (br d, J=8 Hz) and 10.82 (br d, J=8 Hz), total 1H], 8.19-8.27 (m, 1H), [7.80 (d, J=3.2 Hz) and 7.83 (d, J=3.2 Hz), total 1H], [7.65 (d, J=3.3 Hz) and 7.69 (d, J=3.3 Hz), total 1H], 7.28-7.33 (m, 2H), 7.20-7.27 (m, 2H), 7.14-7.19 (m, 1H), [6.31 (ddd, J=11, 8, 4.5 Hz) and 6.44 (ddd, J=11, 8, 4 Hz), total 1H], [4.53 (dd, J=9, 8 Hz) and 4.60 (dd, J=9, 7.5 Hz), total 1H], 3.24 and 3.25 (2 s, total 3H), 3.17 and 3.21 (2 s, total 3H), 2.93 and 3.00 (2 br s, total 3H), [1.14 (d, J=6.5 Hz) and 1.17 (d, J=6.5 Hz), total 3H].
