实验步骤: Lithium aluminum hydride (9 g) is suspended in dry tetrahydrofuran (100 ml) under ice-cooling, and thereto is added dropwise a solution of 2-(1-pyrrolidinyl)carbonylpyrrolidine (33 g) in dry tetrahydrofuran (80 ml). The mixture is refluxed under nitrogen atmosphere for four hours. The mixture is cooled with ice, and thereto is added a saturated aqueous sodium sulfate solution (about 15 ml), and then mixture is further stirred at room temperature for three hours. The precipitated sodium sulfate is removed by filtration, washed well with chloroform. The filtrate and the washings are combined, concentrated under reduced pressure, and evaporated to give 2-(1-pyrrolidinyl)methylpyrrolidine (22 g). cooling The mixture is refluxed under nitrogen atmosphere for four hours The mixture is cooled with ice The precipitated sodium sulfate is removed by filtration washed well with chloroform concentrated under reduced pressure evaporated

实验步骤: In ethanol (300 ml) is suspended 5% palladium-carbon (3 g), and thereto is added 2-(1-pyrrolidinyl)carbonyl-1-benzylpyrrolidine (30 g), and the mixture is subjected to catalytic hydrogenation at room temperature under atmospheric pressure. The mixture is filtered, and the filtrate is concentrated under reduced pressure to remove the solvent to give 2-(1-pyrrolidinyl)carbonylpyrrolidine (about 18 g) as an oily product. is subjected to catalytic hydrogenation at room temperature under atmospheric pressure The mixture is filtered the filtrate is concentrated under reduced pressure to remove the solvent
