Versuchsvorschrift

To a solution of N-{5-[3-butyl-6-(1-methyl-piperidin-4-yloxy)-pyridazin-4-yl]-2-cyclohexyloxy-phenyl}-methanesulfonamide dihydrochloride (0.1 mmol, 59 mg) in DMF (1.0 mL) was added isobutyl bromide (0.2 mmol, 22 μL), and potassium carbonate (0.4 mmol, 56 mg). And the mixture was stirred at 90° C. for 2 hours. It was then diluted with water/EtOAc. The solvent was removed in vacuo and 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 (1.0 mL), 2N HCl in ether (1.0 mL) was added, condensed, triturated with hexanes to provide the title compound (38 mg). LCMS: m/z 574 [M+1]. 1H NMR (400 MHz, CD3OD): δ 7.39 (1H, d), 7.31 (1H, s), 7.25 (1H, d), 7.04 (1H, s), 5.42 (1H, bs), 4.46-4.53 (1H, m), 3.42-3.48 (1H, m), 2.98-3.30 (5H, m), 2.95 (3H, s), 2.90-2.94 (2H, m), 2.69 (3H, s), 2.09-2.30 (6H, m), 1.82-1.88 (2H, m), 1.20-1.69 (11H, m), 0.89-0.93 (6H, m), 0.79 (3H, t).
