Procedure

The isoquinoline-5-carboxylic acid (Lancaster, 0.25 g, 1.4 mmol) was converted to the corresponding acid chloride with 5 mL of thionyl chloride 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 the acid chloride in 30 mL THF were processed as in Example 134B to afford the title compound (98 mg, 0.29 mmol, 27% yield). 1H NMR (300 MHz, CD3OD) δ ppm 2.31 (s, 3H), 2.35 (s, 3H), 3.31 (s, 3H), 3.81 (t, J=5.3 Hz, 2H), 4.50 (t, J=5.3 Hz, 2H), 7.76 (dd, J=7.5, 7.5 Hz, 1H), 8.23 (d, J=8.1 Hz, 1H), 8.48 (d, J=6.4 Hz, 1H), 8.61 (dd, J=7.1, 1.4 Hz, 1H), 9.03 (d, J=6.1 Hz, 1H), 9.27 (d, J=1.0 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, 62.97; H, 5.54; N, 12.07.
