실험 절차

To a solution of 1.28 g of 4-(pyrrolidin-1-ylcarbonyl)aniline obtained in stage b) below in 100 mL of tetrahydrofuran are added, under argon, 1.28 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 1.28 mL of water, 1.28 mL of 15% (by weight) sodium hydroxide solution and 3.85 mL of water. The solid formed is filtered off and washed with ethyl acetate, and the filtrate is concentrated under reduced pressure to give 1.1 g of 4-(pyrrolidin-1-ylmethyl)aniline in the form of a dark yellow oil, the characteristics of which are as follows:
