Chlorosuccinimide → Methyl 3-chloro-5-cyano-4-hydroxybenzoate

Participants

Reaction Steps

Methyl 3-cyano-4-hydroxybenzoate (2.00 g) was dissolved in chloroform (15 mL) and methanol (5 mL), and N-chlorosuccinimide (3.62 g) and 4N hydrochloric acid-ethyl acetate (6.8 mL) were added to the solution, and then the mixture was stirred at room temperature for 1 hour. The solvent was distilled off under reduced pressure and a mixture of methanol and water in a mixing ratio of 9:1 was added, and then the precipitated crystal was washed with water and isopropyl alcohol to obtain the title compound (1.27 g) as a colorless crystal.
