Reaction Conditions:

with 1-acetoxy-1,2-benziodoxol-3-one;potassium acetate in acetonitrile at 80; for 13 h;Reagent/catalyst;Solvent;Temperature;Time;

Steps:

1-23 Synthesis through the following method
General procedure: Add magnetic particles to a dry 50 mL three-neck reaction flask at room temperature, then add 20 mL of anhydrous B.The nitrile was added to the dry acetonitrile with stirring, then trifluoromethyltrimethylsilane (213 mg, 1.5 mmol) was added, then anhydrous potassium acetate (147 mg, 1.5 mmol) was added. Then, the reaction liquid was heated to 80 ° C, aniline (93 mg, 1.0 mmol) was dissolved in 5 mL of anhydrous acetonitrile, and then the aniline solution was slowly added dropwise to the above-mentioned 80 ° C reaction solution by a constant pressure dropping funnel. Approx. 1 hour. After the dropwise addition was completed, the reaction was carried out at 80 ° C for 12 hours. The reaction solution was cooled to room temperature, and the solid was filtered off, and then the reaction mixture was evaporated to dryness to afford the desired product.
