Hunig's base (0.0196 mL, 0.106 mmol) and 3-fluoropiperidine (0.0148 g, 0.106 mmol) were added to N-(3-(2-chloroacetyl)-1H-pyrrolo[2,3-b]pyridin-5-yl)-2,6-difluoro-3-(propylsulfonamido)benzamide (0.005 g, 0.0106 mmol) in EtOH (0.2 mL), which was stirred at 60° C. for 3 hours. The reaction mixture was concentrated under reduced pressure, and the residue was purified via column chromatography (5% to 10% MeOH/DCM) to provide 2,6-difluoro-N-(3-(2-(3-fluoropiperidin-1-yl)acetyl)-1H-pyrrolo[2,3-b]pyridin-5-yl)-3-(propylsulfonamido)benzamide (3 mg, 52.6%). 1H NMR (400 MHz, CD3OD) δ 8.90-8.92 (m, 1H), 8.62-8.63 (m, 1H), 8.60 (s, 1H), 7.63-7.69 (m, 1H), 7.13-7.16 (m, 1H), 4.60-4.80 (m, 1H), 3.76 (s, 2H), 3.08-3.15 (m, 2H), 2.86-2.94 (m, 1H), 2.59-2.79 (m, 4H), 2.50-2.55 (m, 1H), 1.80-1.93 (m, 4H), 1.57-1.71 (m, 2H), 1.04-1.08 (m, 3H); m/z (APCI-pos) M+1=538.1.
