Versuchsvorschrift

To a solution of 0.26 g. (0.001 mole) of 1-[[3-(3-aminopropoxy)phenyl]carbonyl]piperidine in 30 ml. of dry tetrahydrofuran is added 0.23 g. (0.001 mole) of 4-(aminosulfonyl)-3-thiophenecarbonyl chloride. The mixture is allowed to stand at room temperature for 15 minutes. The tetrahydrofuran is removed in a rotary evaporator and the residue is dissolved in 50 ml. of chloroform. The chloroform solution is extracted with 50 ml. of 10% aqueous sodium hydroxide solution followed by 50 ml. of 10% aqueous hydrochloric acid. The chloroform layer is washed with water, is dried over magnesium sulfate and is filtered. The filtrate is evaporated in a rotary evaporator to give 0.15 g. of an amorphous product, m.p. 70°-80° C.; mass spectrum CI m/e 452 MH+.
