Procedure

2,5-Dichloroisonicotinic acid (1.65 g, 0.0086 mol), HATU (3.27 g, 0.0086 mol), and Et3N (2.32 mL, 0.0166 mol) were added to a solution of the title compound of Example 244 (1.85 g, 0.00574 mol) in 29 mL of DMF. The reaction mixture was stirred at room temperature for 3 h. The completion of the reaction was confirmed by monitoring the disappearance of the title compound of Example 246 step 2 in LC/MS. The crude reaction mixture was concentrated to about 10 mL of DMF. Upon addition of water to this DMF residue, a white solid was formed. This white solid was triturated in water for 20 min and filtered. The solid was collected, dissolved in THF, and dried with MgSO4. Removal of the solvent afforded a brown solid that was crystallized from CH3CN to give 2.1 g of the title compound as white needles (yield 73%). 1H NMR (300 MHz, d6-DMSO): 2.86-2.91 (m, 4H), 7.18 (d, 1H, J=1.2 Hz), 7.25 (s, 1H), 7.32-7.36 (m, 4H), 7.52-7.56 (m, 3H), 7.75 (s, 1H), 8.57 (s, 1H), 10.49 (s, 1H). M+1=497.
