Procedure

61 g of dextrorotatory 1-methyl-2-aminomethylpyrrolidine, 465 ccm of chloroform and, in portions, 155 g of 7-methylsulfamoyl-1,4-benzodioxane-5-carbonyl chloride, with the temperature being maintained at 5°-10° C., were introduced into a balloon flask provided with an agitator and a thermometer. After agitation of the mixture and the addition of 1,850 cm3 of water, chloroform was distilled and the remaining solution was filtered. The base was precipitated by the addition of 65 cm3 of 20% ammonia. The crystals formed were dried off, washed and dried. 154 g of dextrorotatory-N-(1-methyl-2-pyrrolidylmethyl)-7-methylsulfamoyl-1,4-benzodioxane-5-carboxamide was produced (M.P.: 187°-188° C.; yield: 78.5%).
