Versuchsvorschrift

10.0 g of 1-chloro-4-(3-chloro-4-methoxybenzyl)amino-6-cyanophthalazine was dissolved in 50 ml 1-methyl-2-pyrrolidone, then 43.32 g of 4-hydroxypiperidine and 10 ml diisopropylethylamine were added thereto, and the mixture was heated at 170° C. for 8 hr. After cooling, ethyl acetate was added thereto, and the mixture was washed 3 times with water and once with brine. After drying over anhydrous magnesium sulfate, the solvent was evaporated. The resulting residue was purified by silica gel column chromatography to give 10.1 g of 1-(4-hydroxypiperidino)-4-(3-chloro-4-methoxybenzyl)amino-6-cyanophthalazine as yellow crystals.
