実験手順

To 375 g (0.86 mole) of 3-tribromomethanesulfonyl benzoic acid were added 1 ml of dimethylformamide and 500 ml of thionyl chloride and the mixture was refluxed for one hour. The reaction mixture was filtered and 3000 ml of hexane was added to the filtrate to precipitate crystals. The crystals were recovered by filtration and dried to obtain 366 g of 3-tribromomethanesulfonyl benzoylchloride (yield 94%, white crystals).
