Abstract:
The present invention relates to a new process for the preparation of N-(2-chloro-pyridin-5-yl-methyl)-ethylene-diamine of the formula (I) (I) in a technically simple manner in high yield and in very good quality. The new process is characterized in that N-(2-chloro-pyridin-5-yl-methyl)-aminoacetonitrile of the formula (II) (II) is reacted with hydrogen in the presence of ammonia and in the presence of a catalyst and also in the presence of a diluent, at temperatures between 0 DEG C. and 100 DEG C. and a pressure between 1 bar and 100 bar.
