Reaction Steps

At room temperature, under N2 and stirring, a solution of 1-[4-(3,5-dichloro-pyridin-4-ylmethyl)-7-methoxy-1H-phthalazine (1.9 g, 5.9 mmoles), prepared as described in example 22, in dry THF (70 ml) was added with triethylamine (2.05 ml, 14.7 mmoles) and cooled at 0° C. Chloroacetyl chloride (0.56 ml, 7.07 mmoles) was dropwise added and a precipitate formed. After 1 night further 50% of triethylamine and chloroacetyl chloride was added, and after 20 hours at room temperature the mixture was poured into water/ice, concentrated and extracted more times with CH2Cl2. The organic phase was washed with water, anhydrified and brought to dryness to give 2.6 g of the title compound (quantitative yield).
