Procedure

An orange suspension of methyl 3-(bromomethyl)-6-(methylsulfonyl)-2-[3-(trifluoromethyl)phenyl]-4-quinolinecarboxylate (1.068 g, 2.126 mmol) and 4-(1-pyrrolidinyl)piperidine (0.492 g, 3.19 mmol) in acetonitrile (14.17 ml) was stirred at room temperature for 16 h. The solvent was removed under reduced pressure. The residue was absorbed onto florisil and was purified via column chromatography (ISCO, 12 g silica, 5-10% methanol/dichloromethane) to give methyl 6-(methylsulfonyl)-3-{[4-(1-pyrrolidinyl)-1-piperidinyl]methyl}-2-[3-(trifluoromethyl)phenyl]-4-quinolinecarboxylate (1.14 g, 88% yield). MS (m/z) 576.2 (M+H+).
