Versuchsvorschrift

3.3 g of 2-(2-methoxy-4-cyanophenoxy)-acetic acid are hydrogenated in 90 ml of a 2:1 (by volume) mixture of methanol and 25% aqueous ammonia in the presence of 1.6 g of Raney nickel for 5 hours at room temperature under normal pressure. After filtering off the catalyst, it is washed with methanol and water and the filtrate is then concentrated to dryness. The resulting solid material is triturated with a small amount of water, filtered off and dried over P2O5 in an exsiccator.
