Sodium Chloride → Methyl 2-chloroquinoline-4-carboxylate

Participants

Reaction Steps

Potassium carbonate (5.55 g, 40.2 mmol) and methyl iodide (1.88 mL, 30.2 mmol) were added to a DMF (25 mL) solution of commercially available 2-chloro-4-quinolinecarboxylic acid (4.17 g, 20.1 mmol), and the mixture was stirred overnight at room temperature in an argon atmosphere. The reaction solution was added to a saturated aqueous solution of sodium chloride, and the deposited crystal was collected by filtration, washed with water, and dried to obtain the title compound (3.53 g, 15.9 mmol) as a pale yellow solid.
