288.4 g (3.392 mol) of 20% aqueous ammonia are introduced into a 1 l reactor and then 618 g (1.696 mol) of 1-dibutylamino-3-chloropropane hydrochloride (assay 66.5%) are added over 10 minutes and at ambient temperature (22±2° C.). The mixture is stirred for 45 minutes at ambient temperature and is left to separate by settling for 30 minutes. The lower aqueous phase (pH=11) is removed and the organic phase is washed with 300 ml of deionized water at ambient temperature. Stirring is carried out for 30 minutes, separation by settling is carried out for 30 minutes and the lower aqueous phase (pH=9) is removed.
