Versuchsvorschrift

0.29 mL (2.3 mmol) of N-ethylmorpholine is added to a stirred suspension of 400 mg (0.7 mmol) of {4-[(4-{[7-methoxy-4-(4-methoxyphenyl)phthalazin-1-yl]amino}piperidin-1-yl)methyl]phenyl}carboxylic acid (dihydrochloride) in 10 mL of tetrahydrofuran at 0° C., followed by dropwise addition of 0.074 mL (0.77 mmol) of ethyl chloroformate. The mixture is stirred for 1 hour at 0° C., and 0.6 mL (3.5 mmol) of a 20% aqueous ammonia solution is then added slowly. The reaction medium is stirred for 20 hours at room temperature and is then concentrated under reduced pressure. 1N sodium hydroxide is added to the residue and the mixture is then extracted with dichloromethane. The organic phase is washed with saturated aqueous sodium chloride solution, dried over anhydrous sodium sulfate and then evaporated under reduced pressure. The residue is purified on a column of silica (eluent: 85/15 (v/v) dichloromethane/methanol). 150 mg of a colourless oil are obtained.
