Reaction Steps

A solution under N2 of 4-chloro-1-(3,5-dichloro-pyridin-4-ylmethyl)-6-methoxy-phthalazine (1.3 g, 3.7 mmoles), prepared as described in example 45, in dry DMF (50 ml) was added with K2CO3 (1.28 g, 9.25 mmoles), palladium acetate (0.017 g, 0.074 mmoles), CuI (0.028 g, 0.15 mmoles), and triphenylphosphine (0.58 g, 0.22 mmoles). After 30 minutes under stirring 4-prop-2-ynyl-morpholine (1.16 g, 9.25 mmoles) was added and the mixture was stirred overnight, poured into water (10 volumes) and extracted twice with ethyl acetate. After decolouring with charcoal, filtering over celite, concentrating and triturating in ethyl ether, 1.15 g of the title compound were obtained (yield: 70%). m.p.: 171.7-172.7° C. (dec.).
