Versuchsvorschrift

A suspension of 1-(3,5-dichloro-pyridin-4-ylmethyl)-6-methoxy-phthalazine (23.5 g, 73.4 mmoles), prepared as described in example 5, and PtO2 hydrate (0.5 g, 2.2 mmoles) in THF (600 ml) was put in a hydrogenator at room temperature and 2 atmospheres. After 22 hours the mixture was filtered over celite and brought to dryness to give 23.8 g of the title compound (stoichiometric yield). m.p.: 181-183° C.
