Procedure

To a solution of 5-[3-butyl-6-(1-methyl-piperidin-4-yloxy)-pyridazin-4-yl]-2-cyclohexyloxy-phenylamine trihydrochloride (0.2 mmol, 110 mg) in DCM (1.0 mL) at 0° C. was added acetyl chloride (0.4 mmol, 29 μL), DIEA (0.4 mmol, 70 μL) and DMAP (5 mg). And the mixture was stirred at room temperature for 1 hour. It was then condensed 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, kept at room temperature for 10 min, condensed, triturated with hexanes to provide the title compound (61 mg). LCMS: m/z 482 [M+1]. 1H NMR (400 MHz, CDCl3): δ 8.43 (1H, s), 7.89 (1H, s), 6.97 (2H, s), 6.81 (1H, s), 5.60 (1H, bs), 4.37-4.43 (1H, m), 3.10-3.45 (4H, m), 2.90-2.95 (2H, m), 2.81 (3H, s), 2.35-2.61 (4H, m), 2.23 (3H, s), 1.25-1.87 (14H, m), 0.83 (3H, t).
