実験手順: 85 g of levorotatory 1-allyl-2-aminomethyl-pyrrolidine, 610 cm3 of chloroform, and gradually, 178 g of 7-methylsulfamoyl-1,4-benzodioxane-5-carbonyl chloride at a temperature of from 5°-10° C. were introduced into a balloon flask provided with an agitator and a thermometer. After agitation of the mixture 1.2 liters of water were added and then chloroform was distilled. The remaining solution was filtered and then the base was precipitated with 70 cm3 of 20% ammonia. The crystals formed were dried off and washed with water. After recrystallization from ethyl acetate, 117 g of levorotatory-N-(1-allyl-2-pyrrolidylmethyl)-7-methylsulfamoyl-1,4-benzodioxane-5-carboxamide was produced (M.P.: 101°-102° C.; yield: 49%). provided with an agitator chloroform was distilled The remaining solution was filtered the base was precipitated with 70 cm3 of 20% ammonia The crystals formed were dried off washed with water After recrystallization from ethyl acetate, 117 g of levorotatory-N-(1-allyl-2-pyrrolidylmethyl)-7-methylsulfamoyl-1,4-benzodioxane-5-carboxamide was produced (M.P.: 101°-102° C.; yield: 49%)

実験手順: 58 g of 1-allyl-2-aminomethyl-pyrrolidine and 360 ml of chloroform were introduced into a balloon flask provided with an agitator and a thermometer and then, with the temperature being maintained at 5°-10° C., 120 g of 7-ethylsulfonyl-1,4-benzodioxane-5-carbonyl chloride was added. After agitation of the mixture and the addition of a liter of water, the chloroform was distilled. The resulting solution was filtered on carbon black and then the base was precipitated by the addition of 40 ml of 30% soda lye. The resulting crystals were dried off, washed with water and then dried. 152 g of N-(1-allyl-2-pyrrolidylmethyl)-7-ethylsulfonyl-1,4-benzodioxane-5-carboxamide was produced (M.P.: 78°-80° C.; yield: 93.4%). 146 g of the resulting base was dissolved hot in 290 ml of absolute alcohol, and then the solution was filtered on carbon black and acidified by the addition of a solution of 13.5 g of hydrochloric acid in 100 ml of absolute alcohol. After cooling the crystals formed were dried off, washed with absolute alcohol and dried and then purified by recrystallization from absolute alcohol. 119.5 g of N-(1-allyl-2-pyrrolidylmethyl)-7-ethylsulfonyl-1,4-benzodioxane-5-carboxamide hydrochloride was produced (M.P.: 138°-140° C.; yield: 75%). provided with an agitator a thermometer and then, with the temperature being maintained at 5°-10° C. the chloroform was distilled The resulting solution was filtered on carbon black the base was precipitated by the addition of 40 ml of 30% soda lye The resulting crystals were dried off washed with water dried

実験手順: 145 g of methyl-7-sulfamoyl-1,4-benzodioxane-5-carboxylate, 48 g of water and 89 g of 1-allyl-2-aminomethyl-pyrrolidine were introduced into a balloon flask provided with a condenser. The mixture was heated on a water bath until a test sample was soluble in dilute acids and then 1 liter of water was added. The precipitated carboxamide was redissolved by acetate formation. The solution formed was filtered on carbon black and then the base was precipitated by the addition of 20% ammonia. The resulting crystals were dried off, washed with water, dried and purified by passing over hydrochloride (M.P.: 228°-230° C.) followed by transformation into a base by treatment with 20% ammonia. 131 g of N-(1-allyl-2-pyrrolidylmethyl)-7-sulfamoyl-1,4-benzodioxane-5-carboxamide was produced (M.P.: 143°-144° C.; yield: 64.8%). The structure was confirmed by nuclear magnetic resonance. provided with a condenser The mixture was heated on a water bath until a test sample The solution formed was filtered on carbon black the base was precipitated by the addition of 20% ammonia The resulting crystals were dried off washed with water dried purified
