Method for the production of NVI-ethyl-α-pyrrolidylmethyl) -2-methoxy -5-sulfamidobenzamide. The subject of the invention is a method for the production of N- (1-ethyl) - α-pyrrolidylmethyl) -2-methoxy-5-sulphamido-benzamide of the formula I, which is suitable for use in the treatment of gastrointestinal diseases and in the field of psychiatry. The method according to the invention consists in that N-ethyl-α The -aminomethylpyrrolidine of the formula II is reacted with phosphorus oxychloride to give N, N ', N "-tris- (1-ethyl-α-pyrrolidylmethyl) -phosphoric triamide of the formula III, and this, optionally after isolation, is reacted with 2-methoxy-5-sulfamidobenzoic acid of the formula 4 Pyridine is preferably used as solvent and reaction medium unless an acid amide of the formula 3 is isolated by reacting N-ethyl-a-aminomethylpyrrolidine of the formula II with oxychloride phosphorus in the dioxane environment can be N, N, N "-tris- (1-ethyl-α-pyrrolidylmethyl) The phosphoric acid mide of formula III is isolated as a mixture of its di- and trihydrochloride. This mixture is further reacted with 2-methoxy-5-sulfamidobenzoic acid of formula 4. The method according to the invention follows the scheme shown in the figure. The method according to the invention, the course of which was unpredictable not only because of the presence of further the amino group in the acid component of formula IV can be practically carried out in a convenient and easy way, as shown in the examples below. Example I. A 1 liter vessel equipped with a stirrer, thermometer, coolers and dropping funnel is introduced 27 g (0.21 mol) of N-ethyl-α-aminomethylpyrrolidine of the formula II and 560 ml of pyridine. A solution of 6.1 g (0.04 moles) of phosphorus oxychloride in 65 ml of pyridine is added dropwise to this solution, maintaining a temperature of 20 ° C, whereby the compound of formula 3 is formed. The mixture is stirred for 1/2 hour and then added. then 14.8 g (0.064 moles) of 2-methoxy-5-sulfamidobenzoic acid of the formula IV, and then the mixture is heated for 4 1/2 hours under reflux. The mixture obtained is concentrated to half its volume under reduced pressure, and the filtrate is evaporated to dryness. The residue is dissolved in 200 ml of water, by adding 40 ml of hydrochloric acid until the pH is 1. The soaked solution is placed in the refrigerator overnight, then filtered, and the precipitate is dried in an oven at 50 ° C. This precipitate dissolves hot in water. A slight insoluble residue is sucked off during cooking and the hot solution is made alkaline with ammonia. The mixture is cooled, filtered, washed with water and dried in an oven at 50 ° C to give 7.5 g of N- (1-ethyl-α-pyrrolidylmethyl) -2-methoxy-5-sulfamidobenzamide at the temperature of mp 179 ° C. 83 58 083 580 Analysis of the nitrogen content with perchloric acid (100%) shows 12.24% nitrogen (calculation: 12.32%). By proceeding analogously to Example I, but by using dioxane instead of pyridine as solvent and medium in the reaction of N-ethyl-aa, minomethylpyrrolidine of formula II with phosphorus oxychloride, an intermediate product is obtained, namely N, N ' Phosphoric acid, N "-tris- (1-ethyl-α-pyrrolidylmethyl-triamide) of formula II in the form of a hygroscopic mixture of di- and trihydrochloride. This mixture is a white crystal slurry gradually floating in the air. This mixture of hydrochlorides with 2-methoxy-5-sulfamidobenzoic acid of formula IV is taken, dried with the exclusion of air, and a sample of this crystalline slurry is weighed to determine the actual content, after which the entire mixture is reacted in a pyridine environment with the theoretically calculated amount of the acid of formula IV, proceeding analogously to Example I. 10 15 PL PL
