Reaktionsschritte

To a solution of 1.22 g of 4-(2-oxo-2-pyrrolidin-1-ylethyl)aniline obtained in stage b) below in 100 mL of tetrahydrofuran are added, under argon, 1.1 g of lithium aluminium hydride. The reaction mixture is stirred for one hour at room temperature and then cooled to 0° C. and treated successively with 1.1 mL of water, 1.1 mL of 15% (by weight) sodium hydroxide solution and 3.4 mL of water. The solid formed is filtered off and washed with ethyl acetate, and the filtrate is concentrated under reduced pressure to give 1.15 g of 4-(2-pyrrolidin-1-ylethyl)aniline, the characteristics of which are as follows:
