Participants

Reaction Steps

To ethyl (5-chloro-2-fluoro-4-((1-methyl-3-indazolylcarbonyl)amino)phenyl)acetate (1.40 g, 3.59 mmol) were added THF (36 ml) and 0.25N NaOH (21.5 ml, 5.39 mmol). The resulting mixture was stirred at room temperature for 6 hours. The reaction mixture was poured in 1N HCl (6.0 ml). The crystals thus precipitated were collected by filtration under reduced pressure, washed with water and dried under reduced pressure to give (5-chloro-2-fluoro-4-((1-methyl-3-indazolylcarbonyl)amino)phenyl)acetic acid (1.23 g, 95%) as a colorless solid.
