실험 절차

To a solution of 3-butyl-4-(4-cyclohexyloxy-phenyl)-6-(piperidin-4-yloxy)-pyridazine dihydrochloride (Example 14, 0.2 mmol, 97 mg) in EtOH (2 mL) was added 1-chloro-2-methyl-2-propanol (0.4 mmol, 44 μL), and potassium carbonate (0.6 mmol, 83 mg). And the mixture was stirred at 50° C. for 4 hours. It was then diluted with water/EtOAc. The organic layers were combined, dried, and condensed in vacuo and the residue was purified by silica gel chromatography (DCM to DCM+10% MeOH) to give a colorless sticky solid, which was dissolved in DCM (2 mL), 1N HCl in ether (2 mL) was added, kept at room temperature for 10 min, condensed, triturated with hexanes to yield 1-{4-[6-butyl-5-(4-cyclohexyloxy-phenyl)-pyridazin-3-yloxy]-piperidin-1-yl}-2-methyl-propan-2-ol dihydrochloride (86 mg, 77% yield). LCMS: m/z 483 [M+1]. 1H NMR (400 MHz, CD3OD): δ 7.53 and 7.62 (1H, s), 7.41-7.46 (2H, m), 7.10-7.14 (2H, m), 5.42-5.52 (1H, m), 4.41-4.46 (1H, m), 3.65-3.83 (2H, m), 3.25-3.47 (3H, m), 3.05-3.12 (2H, m), 2.22-2.55 (5H, m), 1.98-2.03 (2H, m), 1.78-1.83 (2H, m), 1.40-1.63 (7H, m), 1.38 (6H, s), 1.22-1.36 (3H, m), 0.81 (3H, t).
