반응 단계

112 ml of thionyl chloride, 56 g of 7-nitro-1,4-benzodioxane-5-carboxylic acid were introduced into a 250 ml balloon flask provided with a stirrer, a thermometer and a reflux condenser. The mixture was stirred and 1 ml of dimethylformamide was added with heating. After stirring for one hour at the reflux temperature, the excess of thionyl chloride was removed by distillation under vacuum. 61 g of 7-nitro-1,4-benzodioxane-5-carbonyl chloride were obtained (M.P.: 108° C.; yield: 100%).
