The quinoline-5-carboxylic acid (Lancaster, 0.25 g, 1.4 mmol) was converted to quinoline-5-carbonyl chloride using 5 mL SOCl2 using the method described in Example 134A. The product of Example 126A (0.20 g, 1.1 mmol), Et3N (0.3 mL, 2.2 mmol) and quinoline-5-carbonyl chloride in 30 mL THF were processed as in Example 134B to afford the title compound (0.18 g, 0.53 mmol, 49% yield). 1H NMR (300 MHz, CD3OD) δ ppm 2.30 (d, J=0.7 Hz, 3H), 2.34 (s, 3H), 3.31 (s, 3H), 3.80 (t, J=5.1 Hz, 2H), 4.49 (t, J=5.3 Hz, 2H), 7.60 (dd, J=8.6, 4.2 Hz, 1H), 7.83 (dd, J=8.5, 7.1 Hz, 1H), 8.15 (dt, J=8.5, 1.0 Hz, 1H), 8.40 (dd, J=7.3, 1.2 Hz, 1H), 8.87 (dd, J=4.1, 1.7 Hz, 1H), 9.55 (ddd, J=8.8, 1.7, 0.7 Hz, 1H); MS (DCI/NH3) m/z 342 (M+H)+; Anal. calculated for C18H19N3O2S: C, 63.32; H, 5.61; N, 12.31. Found: C, 63.44; H, 5.05; N, 12.10.
