실험 절차

To a solution of 3-butyl-4-(4-cyclohexyloxy-phenyl)-6-(piperidin-4-yloxy)-pyridazine dihydrochloride (Example 14, 2.0 mmol, 965 mg) in DCM (5 mL) was added ethyl acrylate (6.0 mmol, 0.66 mL), and DIEA (6.0 mmol, 1.05 mL). The mixture was stirred at room temperature over night then condensed. The residue was purified by silica gel chromatography (DCM to DCM+10% 2N NH3 in MeOH) to give a colorless sticky solid, which was dissolved in DCM (2.0 mL), 2N HCl in ether (2.0 mL) was added, kept at room temperature for 10 min, condensed, triturated with hexanes to provide the title compound (792 mg). LCMS: m/z 512 [M+2]. 1H NMR (400 MHz, CD3OD): δ 7.30-7.34 (2H, m), 7.01-7.07 (3H, m), 5.47-5.53 (1H, m), 4.37-4.43 (1H, m), 4.20 (2H, q), 3.35-3.70 (5H, m), 2.87-2.95 (5H, m), 2.20-2.35 (4H, m), 1.96-2.03 (2H, m), 1.78-1.84 (2H, m), 1.35-1.64 (7H, m), 1.28 (3H, t), 1.20-1.26 (3H, m), 0.80 (3H, t).
