Procedure

T3P in ethyl acetate (1.273 mL of a 50% solution, 2.001 mmol) was added to a stirred solution of 7-(ethyloxy)-6-[(1-methylethyl)sulfonyl]-3-{[4-(4-morpholinyl)-1-piperidinyl]methyl}-2-[3-(trifluoromethyl)phenyl]-4-quinolinecarboxylic acid (1 g, 1.539 mmol), [(1R)-2,2,2-trifluoro-1-phenylethyl]amine (0.391 g, 1.847 mmol), and N,N-diisopropylethylamine (0.538 mL, 3.08 mmol) in dichloromethane (10 mL). The reaction mixture was stirred for 16 h, diluted with saturated aqueous sodium bicarbonate, and extracted with methylene chloride (three times). The combined organic extracts were washed with saturated sodium bicarbonate, brine, dried, and concentrated in vacuo. The residue was purified via column chromatography (ISCO, 0-5% methanol/methylene chloride) to afford 7-(ethyloxy)-6-[(1-methylethyl)sulfonyl]-3-{[4-(4-morpholinyl)-1-piperidinyl]methyl}-2-[3-(trifluoromethyl)phenyl]-N-[(1R)-2,2,2-trifluoro-1-phenylethyl]-4-quinolinecarboxamide (0.450 g, 34% yield) as a light yellow solid. 1H NMR (400 MHz, DMSO-d6) δ10.00 (br. s., 1H), 8.48 (br. s., 1H), 7.97 (s, 1H), 7.86 (d, J=7.55 Hz, 2H), 7.71-7.78 (m, 2H), 7.60-7.68 (m, 2H), 7.42-7.47 (m, 3H), 6.20 (quin, J=8.81 Hz, 1H), 4.39 (q, J=6.80 Hz, 2H), 3.72-3.86 (m, 1H), 3.50 (br. s., 4H), 3.44 (br. s., 1H), 3.18 (br. s., 1H), 2.39 (br. s., 1H), 2.33 (br. s., 1H), 2.26 (br. s., 4H), 2.11 (br. s., 1H), 1.68 (br. s., 2H), 1.53 (br. s., 1H), 1.44 (t, J=6.80 Hz, 3H), 1.12-1.37 (m, 7H), 0.74-0.99 (m, 2H); MS (m/z) 807.2 (M+H+).
