実験手順

A solution of ceric ammonium nitrate (228 mg, 0.42 mmol) in acetonitrile (1 mL) and water (0.2 mL) was added dropwise to a solution of the product from Step D (102 mg, 0.21 mmol) in acetonitrile (1 mL). The resulting solution was stirred at rt for 2 h and then concentrated at reduced pressure. Trituration of the remaining material with a mixture of CH2Cl2 and water provided E as a light yellow solid (75 mg, 0.15 mmol, 73%): 1H NMR (400 MHz, DMSO-d6) δ 13.05 (br, 1H), 7.95 (d, 2H, J=8), 7.41 (d, 2H, J=8), 7.22 (dd, 2H, J=8, 6), 7.07 (t, 2H, J˜9), 3.87 (m, 4H), 3.77 (t, 2H, J=7), 3.07 (m, 2H), 2.99 (m, 2H), 2.54 (quint., 2H, J=7), 0.75 (t, 3H, J=7) ppm; ESI-MS m/z 490 (M+H)+.
