実験手順

To a stirring mixture of #122 (600 mg, 0.611 mmol, 1.00 eq.) in 15 mL of dichloromethane, diethylamine (5 mL, 50 mmol, 80 eq.) was added. The reaction was allowed to stir at room temperature for 3 hours. Reaction was concentrated in vacuo and mixture was purified by Silica Chromatography (Gradient: 0%-40% methanol in dichloromethane) producing #123 (0.46 g, 99%) as a solid. LC-MS (Protocol Q1): m/z 760.3 [M+H+] retention time=0.83 minutes. 1H NMR (400 MHz, CD3OD), δ 7.14-7.30 (m), 4.70-4.78 (m), 4.56-4.64 (m), 4.05-4.19 (m), 3.87 (dd), 3.79-3.84 (m), 3.72-3.77 (m), 3.62-3.70 (m), 3.46-3.56 (m), 3.37-3.45 (m), 3.33-3.36 (m), 3.16-3.24 (m), 3.09-3.11 (m), 2.98-3.05 (m), 2.95 (d), 2.91 (d), 2.87 (d), 2.83 (d),2.73-2.79 (m), 2.40-2.51 (m), 2.29-2.39 (m), 2.16-2.28 (m), 2.04-2.15 (m), 2.01 (s), 1.73-1.96 (m), 1.50-1.68 (m), 1.47-1.49 (m), 1.46 (s), 1.43 (s), 1.38 (s), 1.35 (d), 1.23-1.32 (m), 1.17-1.22 (m), 1.15 (d), 1.04-1.11 (m), 0.94-1.03 (m), 0.82-0.91 (m).
