This invention also relates to the use of the 6-amino-7-hydroxy-4,5,6,7-tetrahydro-imidazo[4,5,1-jk][1]-benzazepin-2[1H]-one hydrogenation product or a salt thereof to selectively make a stereoisomer of zilpaterol or a salt thereof, as well as the use of such a zilpaterol stereoisomer or salt in methods of treatment and medicaments for animals.
