実験手順
A mixture of 3-butyl-4-(4-cyclohexyloxy-phenyl)-6-(piperidin-4-yloxy)-pyridazine (Example 14, 0.244 mmol, 100 mg) and acrylic acid tert-butyl ester (2 mL) may be stirred at room temperature for 20 h. The organic solvent may be removed in vacuo and the residue is purified by column chromatography on silica gel using 1-2% of MeOH in DCM to give 3-{4-[6-butyl-5-(4-cyclohexyloxy-phenyl)-pyridazin-3-yloxy]-piperidin-1-yl}-propionic acid tert-butyl ester.
