Reaction Steps

To a solution of 3-butyl-4-(4-cyclohexyloxy-phenyl)-6-(piperidin-4-yloxy)-pyridazine dihydrochloride (Example 14, 0.1 mmol, 49 mg) in EtOH (1 mL) was added 2-bromoethanol (0.3 mmol, 22 μL), and potassium carbonate (0.4 mmol, 56 mg). The mixture was stirred at room temperature for 3 hours and 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% 2N ammonia in MeOH) to give a colorless sticky solid, which was dissolved in DCM (1 mL), 1N HCl in ether (1 mL) was added, kept at room temperature for 10 min, condensed, triturated with hexanes to provide the title compound (12 mg). LCMS: m/z 456 [M+2]. 1H NMR (400 MHz, CD3OD): δ 7.78 (1H, s), 7.45-7.49 (2H, m), 7.12-7.17 (2H, m), 5.38-5.57 (1H, m), 4.41-4.48 (1H, m), 3.91-3.95 (2H, m), 3.60-3.81 (2H, m), 3.32-3.47 (4H, m), 3.12-3.17 (2H, m), 2.10-2.59 (5H, m), 1.98-2.04 (2H, m), 1.78-1.84 (2H, m), 1.35-1.63 (7H, m), 1.26-1.33 (2H, m), 0.82 (3H, t).
