2-Bromo-5-chloro-1-(phenylsulfonyl)-1H-pyrrolo[3,2-b]pyridine (20.7 g, 44.6 mmol, prepared as in Example 62, Step 1, but isolated as the free base) in THF (300 mL) was stirred with 1N NaOH (300 mL, 300 mmol) overnight. The reaction mixture was extracted with EtOAc three times. The combined extracts were dried over sodium sulfate, filtered, and concentrated to afford 2-bromo-5-chloro-1H-pyrrolo[3,2-b]pyridine in theoretical yield. LCMS (M+H)+: 233.0 (most abundant).
