Reaction Conditions:
with potassium carbonate;p-toluenesulfonyl chloride in acetonitrile at 20; for 2.5 h;
Steps:
3.2. General Procedure for the Preparation of CarboxylicAcid Anhydride Using TsCl in Conventional System
General procedure: TsCl (0.5 mmol, 0.10 g) was added to the mixture of carboxylic acid (1 mmol) and K2CO3 (1.5 mmol, 0.20 g) in dry CH3CN (5 mL), the reaction mixture was stirred at roomtemperature for the appropriate time (20-180 min, Table 2) until the TsCl was no longer detectable by TLC. After the completion of the reaction, CH2Cl2 or Et2O (2×10 mL) was added to the reaction mixture, stirred, filtered, and the organic layer was dried over CaCl2. The evaporation of the solvent afforded a highly pure product.
