A suspension of methyl 3-(bromomethyl)-6-(ethylsulfonyl)-7-(methyloxy)-2-[3-(trifluoromethyl)phenyl]-4-quinolinecarboxylate (1.983 g, 3.63 mmol) and 4-(4-piperidinyl)morpholine (0.803 g, 4.72 mmol) in acetonitrile (30 mL) was stirred for 3 hours. The solvent was removed under reduced pressure. The residue was dissolved in DMSO and purified via reverse phase HPLC (Biotage RP, 0-50% MeCN/H2O with 0.1% TFA). The fractions containing the product were neutralized with saturated aqueous NaHCO3 and extracted with methylene chloride (3 times). The combined organic extracts were washed with brine, dried over Na2SO4, filtered, and concentrated in vacuo to afford methyl 6-(ethylsulfonyl)-7-(methyloxy)-3-{[4-(4-morpholinyl)-1-piperidinyl]methyl}-2-[3-(trifluoromethyl)phenyl]-4-quinolinecarboxylate (2.0 g, 87% yield). 1H NMR (400 MHz, DMSO-d6) δ 8.38 (s, 1H), 7.98 (s, 1H), 7.90 (t, J=7.91 Hz, 2H), 7.75-7.84 (m, 2H), 4.10 (s, 3H), 4.01 (s, 3H), 3.61 (s, 2H), 3.50-3.58 (m, 6H), 2.63 (d, J=11.04 Hz, 2H), 2.38 (br. s., 4H), 1.93-2.08 (m, 1H), 1.81 (t, J=10.92 Hz, 2H), 1.61 (d, J=11.54 Hz, 2H), 1.22-1.30 (m, 2H), 1.15 (t, J=7.40 Hz, 3H); MS (m/z) 636.2 (M+H+).
