Reaction Steps

1-(3,5-Dichloro-pyridin-4-ylmethyl)-4-phenyl-6-methoxy-phthalazine (0.5 g, 1.26 mmoles), prepared as described in example 47, in THF (40 ml) was added with platinum oxide hydrate (catalytic amount), then hydrogenated in a Parr at 4 atmospheres under stirring for 4 days and at 50° C. for 24 hours. The catalyst was filtered off and the mixture dried to give a solid which flash chromatographed (eluent: petrolatum/ethyl acetate 8:2) giving 0.16 g of the title compound (yield: 32%). m.p.: 175.3-177.3° C.
