Light yellow solid
Synthesis
92-70-6
1779-10-8
In a 1 L three-necked flask, 3-hydroxy-2-naphthalenecarboxylic acid (50 g, 0.27 mol) was dissolved in 600 mL of glacial acetic acid and stirred until completely dissolved. Another 100 mL of glacial acetic acid was taken to dilute the bromine (34 mL, 0.67 mol), and the diluted bromine solution was slowly added dropwise to the reaction solution, controlling the reaction temperature between 20-30 °C. After the dropwise addition was completed, the reaction system was heated up to 120 °C, and the reaction was refluxed for 3 hours. After the reaction was completed, the heating was stopped and the reaction solution was allowed to cool naturally to room temperature. The cooled reaction solution was slowly poured into 3000 mL of ice water, and a large amount of yellow solid was precipitated. The solid product was collected by filtration, and the filter cake was washed with water and dried in an oven to give 84 g of intermediate 2 in 91% yield.
