Sodium Hydroxide → [4-(2,3-Dihydro-1H-pyrrolo[2,3-b]pyridin-4-yloxy)-3-fluorophenyl]amine

Participants

Reaction Steps

50 mg (0.09 mmol) of N-[3-fluoro-4-({1-[(4-methylphenyl)sulfonyl]-2,3-dihydro-1H-pyrrolo[2,3-b]pyridin-4-yl}oxy)phenyl]-4-methylphenylsulfonamide (from example XLV) are dissolved in 1.00 ml of sulfuric acid (95%) and stirred at RT overnight. With ice-cooling, the reaction solution is neutralized with 20% strength aqueous sodium hydroxide solution, and the mixture is extracted three times with ethyl acetate. The organic phase is dried over anhydrous magnesium sulfate and concentrated.
