実験手順

To a solution of 6-[(6-chloropyridin-3-yl)methyl]-3-[(1S,2S)-2-hydroxycyclohexyl]benzo[h]quinazolin-4(3H)-one (2.50 g, 5.95 mmol) in 30 mL of THF under an atmosphere of nitrogen was added methyl zinc chloride (2 M in THF, 5.95 mL, 11.09 mmol) and [1,1′-bis(diphenylphosphino)ferrocene]dichloropalladium(II), 1:1 complex with DCM (0.146 g, 0.179 mmol). The reaction was heated at 50° C. for 18 h, cooled to rt, and slowly treated with water. A beige solid was removed via filtration and the aqueous layer of the filtrate was extracted 2× 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 3-[(1S,2S)-2-hydroxycyclohexyl]-6-[(6-methylpyridin-3-yl)methyl]benzo[h]quinazolin-4(3H)-one that gave proton NMR spectra consistent with theory and a mass ion (ES+) of 400.0 for [M+H]+.
