実験手順

To a solution of 6-[(6-chloropyridin-3-yl)methyl]-3-[(1S,2S)-2-hydroxycyclohexyl]pyrido[3,4-h]quinazolin-4(3H)-one (Example 1, 0.120 g, 0.285 mmol) in 2 mL of DMF was added sodium thiomethoxide (0.100 g, 1.43 mmol). The mixture was heated in a sealed tube at 130° C. for 18 h, cooled to rt, and diluted with ethyl acetate. The organic solution was washed with water and brine, 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 432.9 for [M+H]+: 1H NMR (400 MHz, CDCl3) δ 9.41 (s, 1H), 8.73-8.63 (m, 2H), 8.39 (s, 1H), 8.29-8.19 (m, 1H), 8.09 (s, 1H), 7.32-7.26 (m, 1H), 7.08 (d, J=8.3 Hz, 1H), 4.61 (br s, 1H), 4.50 (s, 2H), 4.05 (br s, 1H), 2.53 (s, 3H), 2.40-2.27 (m, 2H), 2.13-1.75 (m, 3H), 1.55-1.35 (m, 3H).
