To a solution of 1.12 g of 3-(pyrrolidin-1-ylcarbonyl)aniline obtained in stage b) below in 100 mL of tetrahydrofuran are added, under argon, 0.89 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 0.89 mL of water, 0.89 mL of 15% (by weight) sodium hydroxide solution and 2.67 mL of water. The solid formed is filtered off and washed with ethyl acetate, and the filtrate is concentrated under reduced pressure to give 1.02 g of 3-(pyrrolidin-1-ylmethyl)aniline, the characteristics of which are as follows:

1. temperaturecooled to 0° C.
