Procedure

To a solution of 4-[3-butyl-6-(1-methyl-piperidin-4-yloxy)-pyridazin-4-yl]-2-methoxy-phenol (1.0 mmol, 371 mg) in dry THF (3.0 mL) was added cyclohexanol (3.0 mmol, 317 μL) and triphenylphosphine (3.0 mmol, 787 mg). While sonicating, diisopropyl azodicarboxylate (3.0 mmol, 591 μL) was added. And the mixture was sonicated for another 1 hour then condensed. The residue was purified by silica gel chromatography (DCM to DCM+10% MeOH) to afford a colorless sticky solid, which was dissolved in DCM (5.0 mL), 2N HCl in ether (5.0 mL) was added, condensed, triturated with hexanes to provide the title compound (332 mg). LCMS: m/z 455 [M+1]. 1H NMR (400 MHz, CD3OD): δ 7.09 (1H, d), 6.98-7.03 (2H, m), 6.90-6.93 (1H, m), 5.45 (1H, bs), 4.30-4.38 (1H, m), 3.85 (3H, s), 3.10-3.37 (4H, m), 2.90-2.96 (2H, m), 2.79 (3H, s), 2.10-2.35 (4H, m), 1.96-2.03 (2H, m), 1.80-1.87 (2H, m), 1.31-1.63 (8H, m), 1.20-1.29 (2H, m), 0.80 (3H, t).
