Procedure

To a suspension of 360 mg (1.00 mmol) of 2-[3-(5-hydroxy-pyrimidin-2-yl)-benzyl]-6-(1-methyl-1H-pyrazol-4-yl)-2H-pyridazin-3-one in 2 ml THF 394 mg (1.50 mmol) of triphenylphosphine and 242 μl (2.00 mmol) of 4-(2-hydroxyethyl)morpholine are added one after the other. Under ice cooling 294 μl (1.50 mmol) of diisopropylazodicarboxylate are slowly added dropwise. The resulting solution is stirred for 18 hours at room temperature. The reaction mixture is then concentrated in vacuo and the oily residue is dissolved in 2-propanol. The resulting solid of 6-(1-methyl-1H-pyrazol-4-yl)-2-{3-[5-(2-morpholin-4-yl-ethoxy)-pyrimidin-2-yl]-benzyl}-2H-pyridazin-3-one resulted after some time is sucked off, washed with 2-propanol and tert-butylmethylether and dried in vacuo.
