実験手順

To a solution of 3-[(3R,4S)-3-hydroxytetrahydro-2H-pyran-4-yl]-6-[(6-isopropenylpyridin-3-yl)methyl]benzo[h]quinazolin-4(3H)-one (0.042 g, 0.098 mmol) in a mixture of 1 mL of acetone, 1 mL of THF, and 1 mL of water was added ruthenium(II) chloride hydrate (5.5 mg, 0.025 mmol) and sodium periodate (0.084 g, 0.39 mmol). After 1.5 h, the mixture was diluted with water and extracted 3× with dichloromethane. The combined organic fractions were dried over sodium sulfate, filtered, and concentrated in vacuo. The residue was purified via silica gel chromatography, eluting with 0-5% methanol in dichloromethane to provide the title compound that gave proton NMR spectra consistent with theory and a mass ion (ES+) of 460.1763 for [M+H]+ [Calc'd for C25H24N3O4, [M+H]+=430.1761]: 1H NMR (400 MHz, CDCl3) δ 8.89 (d, J=8.1 Hz, 1H), 8.52 (s, 1H), 8.28 (s, 1H), 7.83 (d, J=8.1 Hz, 1H), 7.78 (s, 1H), 7.71 (d, J=8.4 Hz, 1H), 7.65-7.56 (m, 2H), 7.47-7.45 (m, 1H), 4.84-4.78 (m, 1H), 4.33 (s, 2H), 4.26-4.09 (m, 2H), 4.07-4.05 (m, 1H), 3.70 (br s, 1H), 3.57 (t, J=11.0 Hz, 1H), 3.34 (t, J=10.0 Hz, 1H), 2.64 (s, 3H), 2.25-2.20 (m, 1H), 2.01-1.97 (m, 1H).
