Procedure

The compound of example 244 (3.872 mmoles), 4-methyl-6-chloronicotinic acid from step 2 (5.828 mmoles), and HATU (5.844 mmoles) were dissolved in 20 mL DMF followed by the addition of 1.9 mL triethylamine. The mixture was stirred at room temperature overnight. The solvent was then stripped and the residue suspended in water, filtered, and washed with water. The solid was recrystallized from acetonitrile, then redissolved in acetonitrile, decolorized with decolorizing carbon, and dried over anhydrous MgSO4. The solvent was then stripped down to a solid. Mp: 280-284° C. 1H NMR (d6-DMSO, 400 MHz): δ 2.28 (s, 3H); 2.84-2.98 (m, 4H); 7.25-7.44 (m, 6H); 7.49 (s, 1H); 7.51-7.62 (m, 3H); 8.35 (s, 1H); 10.31 (s, 1H). 13C NMR (DMSO, 100 MHz): δ 19.13, 20.35, 29.67, 115.01, 117.07, 117.30, 120.08, 121.34, 126.19, 126.60, 128.72, 128.81, 129.58, 132.80, 133.42, 136.81, 136.84, 137.64, 139.71, 143.19, 148.42, 149.96, 151.59, 161.44, 163.88, 164.47, 164.78.
