Participants

Reaction Steps

The title compound of Example 244 (0.757 mmoles), 5-chloro-2-morpholin-4-ylisonicotinic acid, (1.38 mmoles), and HATU (1.57 mmoles) were dissolved in 5 mL DMF followed by the addition of 0.4 mL of triethylamine. The mixture was stirred at room temperature for 3 hrs and partially stripped of DMF. The reaction mixture was then added to water, filtered, and washed with water. The solid was dissolved in THF, decolorized with decolorizing carbon, and dried over anhydrous MgSO4. The THF was stripped and the solid triturated in diethyl ether three times, then triturated in ethanol, and twice more with acetonitrile, filtered and dried under vacuum. Mp: 309–313° C. 1H NMR (d6-DMSO, 400 MHz): δ 2.80–2.95 (m, 4H); 3.42 (t, 4H, J=5 Hz); 3.62 (t, 4H, J=5 Hz); 6.88 (s, 1H); 7.17–7.21 (m, 1H); 7.23–7.41 (m, 5H); 7.49–7.58 (m, 3H); 8.14 (s, 1H); 10.31 (s, 1H). 13C NMR (d6-DMSO, 100 MHz): δ 20.34, 29.70, 45.74, 66.50, 106.55, 114.97, 115.87, 117.09, 117.32, 120.05, 121.41, 126.67, 128.64, 128.73, 129.62, 133.47, 136.80, 136.82, 137.48, 139.64, 143.21, 145.28, 147.54, 158.30, 161.39, 163.85, 164.45.
