A solution of 1-(chloromethyl)-4-propylpyrrolidin-2-one x63 (41.34 g, 0.235 mol) in toluene (350 ml) is added dropwise at −78° C. to liquid ammonia (300 ml). At the end of the addition, the temperature is raised slowly to room temperature, and ammonia of the crude mixture is allowed to distill at room temperature overnight. Filtration of the reaction mixture and subsequent evaporation lead to 55 g of the crude 1-(aminomethyl)-4-propylpyrrolidin-2-one x76 which is used without further purification.
