Reaction Steps

Triethylsilane (0.0590 mL, 0.355 mmol) and trifluoroacetic acid (“TFA”; 0.0180 mL, 0.234 mmol) were added to N-(3-((4-chlorophenyl)(hydroxy)methyl)-1H-pyrrolo[2,3-b]pyridin-5-yl)-2,6-difluoro-3-(propylsulfonamido)benzamide (0.005 g, 0.009 mmol) in CH3CN (1 mL). The solution was warmed to 80° C. for 10 minutes. The solution was cooled and concentrated under reduced pressure to provide N-(3-(4-chlorobenzyl)-1H-pyrrolo[2,3-b]pyridin-5-yl)-2,6-difluoro-3-(propylsulfonamido)benzamide (4 mg, 82.5%). 1H NMR (400 MHz, CD3OD) δ 8.63-8.44 (m, 1H), 8.30-8.32 (m, 1H), 7.62-7.68 (m, 1H), 7.35 (s, 1H), 7.27 (s, 4H), 7.10-7.15 (m, 1H), 4.11 (s, 2H), 3.09-3.13 (m, 2H), 1.84-1.89 (m, 2H), 1.03-1.07 (m, 3H); m/z (APCI-pos) M+1=519.1.
