Reaction Conditions:
with N-benzyl-N,N,N-triethylammonium chloride;potassium iodide;sodium hydroxide in water at 30 - 70; for 2 h;Reagent/catalyst;
Steps:
4 Preparation of Compound III
Add 4.71g of 4-amino-3-fluorophenol, 4.13g of sodium hydroxide, 32.11g of potassium iodide, 22.78g of triethylbenzylammonium chloride, 500ml of water to the reaction flask, and heat to 30 ° C to stir and dissolve. When the temperature reaches At 70 ° C, 21.61 g of compound III was added dropwise, and the reaction was stirred for 2 h. After completion of the reaction, the mixture was cooled, washed with a 2% aqueous sodium hydroxide solution, and the mixture was separated. The organic layer was recrystallized from ethanol to give compound IV 25.48 g, product yield 97.5%, purity 99.96%.
