実験手順

According to general procedure A, from #83 (552 mg, 0.555 mmol, 1 eq.) in dichloromethane (10 mL, 0.05 M) and diethylamine (10 mL) was synthesized the crude desired material, which was diluted with methanol, concentrated in vacuo onto silica, and purified by silica gel chromatography (Gradient: 0% to 10% methanol in dichloromethane) to give #84 (406 mg, 95%) as a white solid. LC-MS: m/z 772.8 [M+H+], retention time=1.35 minutes; HPLC (Protocol A): 774.4 [M+H+], retention time=7.390 minutes; 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], 7.78-7.84 (m, 2H), [7.65 (d, J=3.1 Hz) and 7.69 (d, J=3.3 Hz), total 1H], 7.29-7.34 (m, 2H), 7.20-7.28 (m, 2H), 7.14-7.19 (m, 1H), 6.27-6.35 and 6.40-6.48 (2 m, total 1H), [4.51 (dd, J=9, 8 Hz) and 4.57 (dd, J=9, 8 Hz), total 1H], 3.24 and 3.25 (2 s, total 3H), 3.16 and 3.21 (2 s, total 3H), 2.94 and 3.00 (2 br s, total 3H), 2.09 and 2.10 (2 s, total 3H), 1.08 and 1.09 (2 s, total 3H), 0.73-0.80 (m, 3H).

後処理

  1. concentrationconcentrated in vacuo onto silica
  2. custompurified by silica gel chromatography (Gradient: 0% to 10% methanol in dichloromethane)
