Reaktionsschritte

243 g of thionyl chloride, a few drops of dimethyl formamide and 139 g of 7-ethylsulfonyl-1,4-benzodioxane-5-carboxylic acid were introduced into a balloon flask provided with a condenser. The mixture was heated and then the thionyl chloride in excess was distilled off under vacuum. 148 g of 7-ethylsulfonyl-1,4-benzodioxane-5-carbonyl chloride were obtained (M.P.: 146°-147° C.; yield: 100%).
