Procedure

The o-dodecanesulfonylbenzoic acid (30.0 g, 0.084 mol) was dissolved in 100 ml of methylene chloride, then 0.5 ml of N,N-dimethylformamide was added, and they were stirred at room temperature. Then 12 ml of oxalyl chloride was added dropwise over 15 min, and after the addition the reaction mixture was stirred for 1 hour. The reaction solution was concentrated, to obtain o-dodecanesulfonylbenzoyl chloride.
