Versuchsvorschrift

To a solution of 3-{4-[6-butyl-5-(4-cyclohexyloxy-phenyl)-pyridazin-3-yloxy]-piperidin-1-yl}-propionic acid ethyl ester dihydrochloride (Example 15, 1.0 mmol, 583 mg) in THF-MeOH—H2O (1:1:1, 3 mL) was added LiOH (20 mmol, 480 mg). The mixture was stirred at 100° C. for 10 min. The mixture was then diluted with water/EtOAc and neutralized with acetic acid. The organic layers combined, dried, and condensed in vacuo, and the residue was dissolved in DMF (2 mL). Dimethylamine hydrochloride (3.0 mmol, 245 mg), HBTU (3.0 mmol, 1.14 g), DIEA (3.0 mmol, 0.53 mL) were added to the mixture, and the mixture was stirred at 100° C. for 2 hours. It was then diluted with water/EtOAc and neutralized with acetic acid. 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 (2 mL), 2N HCl in ether (2 mL) was added, kept at room temperature for 10 min, condensed, triturated with hexanes to provide the title compound (279 mg). LCMS: m/z 510 [M+1]. 1H NMR (400 MHz, CD3OD): δ 7.31-7.35 (2H, m), 7.01-7.07 (3H, m), 5.46-5.52 (1H, m), 4.37-4.43 (1H, m), 3.35-3.50 (5H, m), 3.03 (6H, s), 2.87-2.95 (5H, m), 2.20-2.35 (4H, m), 1.96-2.03 (2H, m), 1.78-1.84 (2H, m), 1.27-1.63 (8H, m), 1.20-1.24 (2H, m), 0.80 (3H, t).
