실험 절차

13 g of 7-ethylsulfonyl-1,4-benzodioxane-5-carboxylic acid, 300 ml of tetrahydrofuran and 13 g of carbonyldiimidazole were introduced into a balloon flask provided with an agitator, a thermometer and a condenser. The mixture was agitated at ambient temperature and then 9.5 g of 1-ethyl-2-aminomethylpyrrolidine was added. Agitation was maintained at ambient temperature and then the solvent was evaporated under vacuum. The crystals produced were washed with water and then dried. 14 g of N-(1-ethyl-2-pyrrolidylmethyl)-7-ethylsulfonyl-1,4-benzodioxane-5-carboxamide was produced (M.P.: 118°-119° C.; yield: 73.8%)
