ABSTRACT:
2-Amino-5-aminomethyl-pyridine, of the formula ##STR1## can be prepared by reacting substituted methylene-glutaconic acid dinitrile of the formula ##STR2## having the meaning of R.sup.1 as given in the general description, at from 50.degree. to 200.degree. C., initially with from 3 to 20 mol of ammonia and then, in the presence of a hydrogenation catalyst, with hydrogen. The hydrogen is present an a partial pressure of from 10 to 250 bar. The reaction can be carried out with or without solvent.
