Reaction Steps
75 mg (0.68 mmol) of 3-chloro-1,2-propanediol and 322 mg (0.99 mmol) of caesium carbonate are added to 150 mg (0.41 mmol) of 2-[3-(5-hydroxy-pyrimidin-2-yl)benzyl]-6-(1-methyl-1H-pyrazol-4-yl)-2H-pyridazin-3-one, and the mixture is suspended in acetone. The reaction mixture is stirred at 80° C. for 5 days. Water is added to the reaction mixture, which is then extracted a number of times with ethyl acetate, dried over sodium sulfate and evaporated. The crude product is purified by means of column chromatography on silica gel.
