Reaction Conditions:

with thionyl chloride in dichloromethane for 5 h;Heating / reflux;

Steps:

1
4-t-butylphenyl sulfonic acid (1Og, 0.05 mol) and thionyl chloride (6.7g, 0.06 mol) were dissolved in dichloromethane (100 mi) and refluxed for 5 hours. After completion of the reaction, to the residue, dichloromethane (200 mi) was added dropwise and water (100 mi) was added for washing. Then, the residue was dried with anhydrous manganese (10Og), filtered and concentrated to obtain 9.7 g of 4-t-butylphenyl sulfonyl chloride (yield = 90%).
