Yield	Reaction Conditions	Operation in experiment
87%		Into a 500 ml three-necked flask, 100 mL of acetic acid was added, and Compound 2 (20 g, 0.11 mol) was added dropwise to a 100 mL aqueous solution of 40% hydrogen bromide at 0C. The reaction was completed after 30 minutes of dropwise addition. A 50 ml aqueous solution of sodium nitrite (20.7 g, 0.33 mol) was added dropwise at a controlled temperature of 0C. After 30 minutes of reaction, the reaction is complete and it is quenched by the dropwise addition of 30 ml of 10% sodium bisulfite solution. Ethyl acetate extraction (200ml×2), dried over 20g of anhydrous sodium sulfate, The mixture was concentrated by suction filtration to obtain a white solid compound 3 (23.3 g, yield 87%).
