Hydrochloric Acid → (3-Bromo-4-((1-isoquinolinylcarbonyl)amino)phenyl)acetic acid

Participants

Reaction Steps

Ethyl (3-bromo-4-((1-isoquinolinylcarbonyl)amino)phenyl)acetate (1.64 g, 3.97 mmol) was dissolved in THF (40 ml). To the resulting solution was added 0.25N NaOH (24.0 ml, 5.95 mmol), and the mixture was stirred at room temperature for 8 hours. The reaction mixture was poured into 1N HCl (50 ml) to acidify the mixture. The crystals thus precipitated were collected by filtration under reduced pressure, washed with water, and dried under reduced pressure to give (3-bromo-4-((1-isoquinolinylcarbonyl)amino)phenyl)acetic acid (1.50 g, 98%) as a pale yellow solid.
