Synthesis method
By4-methoxy-2-Nitroaniline is obtained by cyclization reaction. Add glycerol into the reaction pot and heat at 70℃Add sulfuric acid below and then put in4-Methoxy-2-Nitroaniline. at75-80℃After insulating, add an aqueous solution of potassium iodide and iodine, and raise the temperature to 125℃, and keep warm until the reaction reaches the end point. Dilute with ice water and incubate at 35℃The following is neutralized with sodium hydroxide solution pH The value is3.5, filter, wash to pHValue is 5, got6-Methoxy-8-nitroquinoline. The yield is 90%.
Purpose
This product can be used as an intermediate for the antimalarial drug primaquine phosphate.
