Piperidine (0.0105 mL, 0.106 mmol) was 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 1 hour. The reaction mixture was cooled and concentrated under reduced pressure. The residue was purified via column chromatography (10% MeOH/EtOAc, to 30% MeOH (7N NH3/EtOAc). The pooled fractions were taken up in 10% MeOH/DCM and filtered to provide 2,6-difluoro-N-(3-(2-(piperidin-1-yl)acetyl)-1H-pyrrolo[2,3-b]pyridin-5-yl)-3-(propylsulfonamido)benzamide (3 mg, 54.4%). 1H NMR (400 MHz, CD3OD) δ 9.05-9.07 (m, 1H), 8.54-8.57 (m, 1H), 8.44 (s, 1H), 7.63-7.69 (m, 1H), 7.12-7.17 (m, 1H), 4.71 (s, 2H), 3.59 (s, 2H), 3.10-3.14 (m, 2H), 1.92-1.99 (m, 6H), 1.84-1.90 (m, 2H), 1.04-1.08 (m, 3H); m/z (APCI-pos) M+1=520.2.
