실험 절차
To 3-tribromomethanesulfonylbenzoic acid (B) obtained in the above-described (Step 1) are added dimethylformamide and thionyl chloride and the mixture is refluxed for one hour. The reaction mixture is filtered, and hexane is added to the filtrate to deposit crystals. The crystals are recovered by filtration and dried to obtain 3-tribromomethanesulfonyl benzoylchloride (C) as white crystals.
