実験手順

Methyl 3-(bromomethyl)-6-(methylsulfonyl)-2-[3-(trifluoromethyl)phenyl]-4-quinolinecarboxylate (2 g, 3.98 mmol), 4-piperidone HCl salt (0.648 g, 4.78 mmol), N,N-diisopropylethylamine (1.53 mL, 8.76 mmol) in acetonitrile (13.27 mL) was heated to 50° C. overnight. The solvent was removed under reduced pressure. The residue was diluted with Na2CO3 and extracted with methylene chloride (four times). The combined organic extracts were washed with brine, dried over Na2SO4, filtered and concentrated in vacuo. The residue was purified via column chromatography (ISCO, 40 g silica, 5-100% ethyl acetate/hexanes) to afford methyl 6-(methylsulfonyl)-3-[(4-oxo-1-piperidinyl)methyl]-2-[3-(trifluoromethyl)phenyl]-4-quinolinecarboxylate (1.051 g, 51% yield). MS (m/z) 521.0 (M+H+).
